Duplicate entry error

On resuming my incomplete form, and then finishing and submitting it, I get the following error message. I am testing this before sending it to client

Sorry for inconvenience this may caused you.

Mentioned issue can not be recreated on our side. It looks like it was a temporary issue.

Please let us know if the same issue happens again. 

Still no luck. And it takes about two minutes to return this error message.

Am I doing something wrong with the "first form" (http://form.jotformeu.com/form/52422565368358)

This is the url for the "Main Form": http://form.jotformeu.com/form/52303081547348

Help!!

Thanks

I was able to reproduce the problem, let me report this to our developers

Thank you - look forward to hearing from you

Our developers have fixed this issue, if the issue persists in your end, then consider to rebuild the google integration.

The problem is still there. It only applies to this/these forms, not to any others and I haven't done anything different. 

What does "rebuild the google integration mean" and what do I have to do?

Thanks

Now the response I get on submitting the form is:

Hi,

Apologies for the inconvenience, what my manager meant is that you remove the Google Spreadsheet integration then re-add it again:

Here's the tutorial on how to integrate your Google Spreadsheet: https://www.jotform.com/help/228-How-to-Integrate-Form-with-Google-Spreadsheet. Please note that it will create a new spreadsheet but will load all the existing submissions of the form.

You can also try cloning your form and see if the cloned form will have the same problem, here's a guide on how to clone it: https://www.jotform.com/help/27-How-to-clone-an-existing-form-from-your-account 

Do let us know if that works.

Hi, I "disintegrated" Google spreadsheet and now everything's working. Thanks very much for all your help. :)
