JotForm is a free online form builder which helps you create online forms without writing a single line of code. No sign-up required.
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.
The issue might be related to conflicts between form code and other scripts on your web page. In order to fix this, use an iFrame version of the form to avoid possible conflicts.
