Green button is missing
The green button should appear on the Form when it's visited via a link the add-on provides.
This link is either emailed directly to the recipient (for Single Signatures), or is copied to the Form Owner's clipboard so they can paste in an email or as a link on a website etc. It can be retrieved at any time by the Form owner from the "See pending" area of the add-on.
The standard Form "Send" menu options unfortunately won't load any signing features or green buttons.
If you're using a link from the add-on and it's still not loading the green button, please forward that to us so we can check why.
Please also let us know what internet browser you are using so we can check compatibility.
Form requires log-in
Most browsers unfortunately won't allow the Signature add-on to work when the Form requires the user to be logged-in.
These features usually are:
File Upload questions
"Restrict to users in ... and its trusted organisations"
"Limit to 1 response"
As the Form's owner, please remove these settings/items and re-try activating the Form for signature collection.
No Form access / We don't have access to the Form or Sheet
The add-on adds a "bot" account as an editor on the Form (and Sheet for Multiple Signatures) so it can insert additional information.
Occasionally this access is removed by a user or policy etc., and in rare case it isn't applied correctly! We encourage Form owners to use the "Test" button that's presented straight after signing is activated.
If access is missing, you can resolve it by adding our bot account "email@example.com" as a Contributor in the Form, and as an Editor in the Response Sheet.
The link will immediately start working again.
Accounts error / Not loading / The add-on is receiving mixed messages
When the add-on is used, Google may inadvertently say one account is using it rather than the other. This can easily lead to errors so we prevent you from continuing.
There are three solutions:
Use a Chrome Profile with just one account logged-in (this is our preferred method)
Open a new Private or Incognito browsing window and visit drive.google.com. You'll be asked to log in before you can continue to your Form
Log out of Google, then log back in with just one account
Response Sheet missing
"Response Sheet missing" will appear when the Form doesn't have a Google Spreadsheet attached.
A standard Google feature of Forms is to attach a Google Spreadsheet to store responses. We use this Sheet also as the actual signature data location so we don't store any of your users' personal information.
As the owner of the Form, open the "Responses" tab, then click the green Google Sheets icon to attach a Response Sheet.
Malformed UTF-8 content / Link error
If you receive this error, the link you are using has been truncated. This occasionally happens when emailed; email programs might change the link's format.
If you are the Form's owner, please always "beautify" the link in an email by pressing Ctrl+k. This will also allow you to make it appear better looking.
You can get the link again at any time from the "See pending" area of the add-on.Please re-send the link to your users so they have the correct version.
If you are not the Form's owner, please contact them and advise them that they need to re-send you the link, or instruct them to read this help section.
No signatures available
The error message " ... (the account holder of this Form's signatures) has no signatures available." refers to the current balance of signature tokens in the Form owner's account.
If you are not the Form owner, please ask them to increase their balance or visit this help page.
If you are the Form owner, 10 signatures are included when installing the add-on so you can get started. Each month you're topped-up to 3 also.
If you need to collect more signatures than these limits, you can purchase them within the add-on under "Get more signatures", or on our bulk-buy page for a discounted rate (this is also linked within the "Get more signatures" tab).
We use simple sales to keep the add-on funded. We don't show advertisements or sell any information.
Multiple Signatures Form with hundreds of responses has stopped working
Occasionally Sheets stop responding to external API's like ours. We usually see this starting to occur at around 500 responses.
When your Form approaches 500 signatures, we recommend switching out the Response Sheet for a new one.
There are two options:
Create a new Form and Response Sheet
(This will mean a new signing link to give to people)
2. Unlink the existing Response Sheet and link a new one
To do option 2:
In your Google Form, visit the Responses area and click the green Sheets icon, and choose to Unlink.
Then delete all responses from the Form itself - responses already received are still stored in the existing Google Spreadsheet which you'll keep.
Then click the green Sheets icon again and create a new Response Sheet.
This lets you continue as before, using the same Form and signing link.
Keep the old Response Sheet - the add-on should be able to access it again after a little time. The contents can also be copied to a new Sheet and viewed.
(You'll visit the "Dashboard" from any View link, or the "See pending" area of the add-on, and paste the old Sheet's URL to view the contents)
drive.google.com refused to connect
Log out of Google
Log back in with just the one account you'll be using with Forms
This is a well known issue in the Google add-ons community and Google are working on it. It's related to having two or more accounts logged-in at once, and the permissions are being picked up from the wrong one
General permission reset
General errors can be a result of incomplete permissions. The first thing we recommend for nearly every error is as follows
Now you can re-open your Form
Close Signature if open
Open Signature, and you'll be prompted to give permission (pictured)
If you aren't prompted for permission, please revisit from the first step
Accept the access/permission requests
We recommend cancelling and re-creating any Signatures, so they'll have all the right permissions
Multiple Signatures Response Sheet has "Pending"
Pending means one of two things:
We've received a signature but couldn't find an appropriate place to put it
Your user didn't sign
If it's been more then a day, it's the latter
Click the Pending link - this takes you to a dashboard
You can pick the correct place for any existing signatures we hold, then draft an email template and easily send this to everyone that's missed the signing process. When they do, Pending will change to View Signature
Signature isn't an option in the jigsaw-piece menu
The add-on isn't installed, or hasn't loaded
Try refreshing and waiting a moment. If it's still missing, follow the Installing steps
"Start" isn't there, only "Help"
It's installed, but hasn't loaded yet. Wait a moment, then use the jigsaw-piece menu again
Or refresh the page if it's being particularly stubborn
Stuck at "Checking..."
Wait up to a minute - this can take a little longer as we're creating an account for you
If it's been a minute, there may be a problem. Usually the permissions haven't come through completely
We recommend uninstalling, and reinstalling the add-on to get the security prompts to appear. It only takes about 30 seconds
To uninstall, follow the steps at
You'll see that the "Add" button in the marketplace will now say "Uninstall"
When you follow those steps again to reinstall, take note of whether you receive the Google security pop-up, and ensure you accept it
(If you look at the Youtube video in the above link, you'll see the prompts appear about 25 seconds in)
It may pop up when you first try to open the add-on, rather than when it's installed
If you don't get any security prompt, it might be blocked by your browser. We recommend Chrome, but any current browser should be fine. Internet Explorer isn't recommended
Problems with signing
A signatory will see this screen in the following cases
The person who requested the signature has since deleted their request; if so, this isn't an error
We couldn't automatically pair the signatory with the signature request
Ensure you're using a link that we created
Email them for me | the signatory was sent an email from us - this email contains a link - use that
I'll contact them myself | the signatory wasn't sent anything directly by us - you were provided a link to copy and send on yourself. You can get this again by opening the add-on, clicking on Pending, and using the controls in that menu. Send that link to your signatory
A signatory will see this screen if we no longer have access to the Editor's Form. We need access to be able to append the signature to the Form and/or Response Sheet
This is a result of us being removed as Editors/Contributors. Removal is usually a manual process, but if you are the Editor and are coming across this regularly, please check if you have any other apps which might change permissions on your Google files
We provide a note which will pop-up when the Editor opens the add-on. The Editor will need to remove and recreate the signature request which will reapply the necessary access rights
Form isn't accepting signatures
A signatory will see this screen on a Multiple Signature attempt if the Form Editor has 0 signatures remaining
It is also given if a link is used which refers to any form which isn't accepting Multiple Signatures
The Form Editor can obtain more signatures, and signing will automatically continue
