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 have checked your form using the direct link https://www.jotform.com/form/62505680949162 and I can see it works, below is a screen-cast of my test:
Seems like you are referring to the embedded version of your form, if so, please provide us the link to the webpage where you've embedded your form, we will be glad to check and find why it does not go to the next page.
Also, if possible, please try embedding your form using the iFrame code as it will help you to avoid any conflict between the form's code and the existing code in your website, here is the guide: Getting-the-form-iFrame-code
We will wait for your response.
