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.
This is because you have already used the tab on the specific page that you are looking for which is why it's no longer appearing on your list. You will need to modify your facebook page and find the tab with embedded form. You can edit your Facebook tab there where your form is. You may also remove the tab and then reintegrate it again through the form builder.
If you have questions, please let us know.
