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.
As I check your JotForm titled "Questionare", I notice that there is a Submit button after phone number field in which the form is submitting without letting to enter the further information.
You may want to have multiple pages on your JotForm by placing a page break for easy access to the form. Please refer to the guide that can help you in creating multi-page forms.
Hope this information helps!
