Are you getting this error message after you submit your form?
This happens when you set your form limits. I did check your last edited form "Registration Form 2" but did not find any issue with that. It is configured correctly and you should not get this error message.
The other two forms you have in your account, seems to have "Unique Question" set. Please check the screenshots below:
Please take a look at the following guide for more information on the "Unique Question" feature: https://www.jotform.com/help/223-How-to-set-Form-Limits-Based-on-a-Unique-Question
Please remove the selected field form the "Unique Question" form limit and that should solve your problem.
Do get back to us if the issue persists.
