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.
Sorry but I don't quite get your question. Would you mind elaborating it further?
Perhaps it is related with the limits you set on your form like "Unique Submissions". That's usually the default error message thrown once a unique question is enabled on the form. Here's a guide on how to disable that: http://www.jotform.com/help/64-What-does-Unique-Submission-Mean?
If that's not what you mean, kindly provide more details.
