Is it possible to direct the user to a "Sign Up" link?

Is it possible to direct the user to a "Sign Up" link when they get this error?

Please elaborate on the error that you are getting so that we can debug further and guide you.

@j21frye,

If you are referring to the following error message, unfortunately, it is not possible to redirect the form to another website.

If you are referring to a different error message, please let us know. We will be happy to assist. 

Ok, thanks for getting back to me. Follow up question here:
So my form links to a google sheet which runs a script that sends a
document to the user who fills in the form.

On the form, the users have three different options to choose from (1) Editable document (2) PDF document (3) Both.

On users' first submissions, I'd like all options available. when they return for a second (or more) time, I'd like the choices (1) and (3) grayed out and to show a "Sign Up" link  that points them to my Weebly registration page. 

Could you help my figure out how to do that?

I'm sorry, but I didn't get what is the actual question in your last reply?

Thank you!

Here's a mock up of what I'm describing

I understand that you want to enable all the options when the user submits the form for the first time. If the same user tries to submit the form again, you want to enable only PDF option and display Sign-up page link. If so, please note that it is not possible to check if the submission is duplicate before submitting the form and to disable the options.

It seems that your requirement needs a custom form that can be achieved by getting the full source code of the form. You may customize the form to disable/enable the options by using some custom scripts and link the form to an external database to check the existing data. If you are not comfortable with programming, you may hire a programmer from Upwork or Freelancer to achieve your requirement.  

Thank you!

Thank you for your response. Is there no work around to this so I don't
have to hire a freelancer?
Is it possible to display a link if a user tries to submit a form with the
same email address?
...

We do have a Unique question option, which checks if entered data in a certain field was previously entered, for example, email:

You can find in the Settings page of your form.

Let us know if you have further questions.

Thank you!

Thank you! If a user tries to submit a form with the same email, can a link to "Sign Up" be prompted?

Unfortunately, that is not possible, there isn't a condition that could check that. That option will only stop the user from submitting the form when the same email address is used.

Thank you!
