What is JotForm?
JotForm is a free online form builder which helps you create online forms without writing a single line of code. No sign-up required.
At JotForm, we want to make sure that you’re getting the online form builder help that you need. Our friendly customer support team is available 24/7.
We believe that if one user has a question, there could be more users who may have the same question. This is why many of our support forum threads are public and available to be searched and viewed. If you’d like help immediately, feel free to search for a similar question, or submit your question or concern.
May we know what specific errors or warning message you are getting? That would help us better to understand the problem.
I went ahead to check your form and I noticed that you have enabled the "Unique Submission" option to "Check cookies and IP".
Please note that a user will NOT be able to make multiple submissions, that feature will prevent users who previously made a submission to make another one if they are using the same browser and device. You can disable that option/feature to enable multiple submission.
To learn more about that function, you can check this guide: https://www.jotform.com/help/64-How-to-Set-Unique-Submissions-on-a-Form
Let us know if that resolves your problem.
