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.
Upon checking your latest form, it does not have any submit button anywhere, that is why your users can't submit it:
You need to add a submit button for your users to submit the form. You can find it under the "Basic Fields" section, simply drag and drop it on your form.
Let us know if that fixes your problem.
