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.
That's probably because of the form caching issues. Please try doing the following:
a. Close the form builder
b. Logout from your account
c. Clear your browser's cache and cookies for Jotform
d. Login again to your account
e. Clear your form's cache. Here's how you can do it: http://www.jotform.com/help/229-How-to-Clear-your-Form-Cache.
f. Now, do the changes to your form and let us know if the problem persists.
