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.
I did check the web page URL where you have embedded your form and it seems to work as expected. I was able to submit the form without any problem. Please check the screenshot below:
Do you get any error message when you submit your form?
I would suggest you to test your form again and get back to us if the issue persists.
