What is JotForm?
JotForm is a free online form builder which helps you create online forms without writing a single line of code. No sign-up required.
At JotForm, we want to make sure that you’re getting the online form builder help that you need. Our friendly customer support team is available 24/7.
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.
Please refer to the user guide -How-to-create-a-Custom-URL-of-a-form
Please type something first in the custom URL box, before the 'Save' button will appear.
I understand it might be confusing at first, but we have designed it this way because some users from before had been mistaking that 'Save' button as a way to save the form link for a different purpose.
Let us know if you need further assistance.
