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.
You can not change the form ID number, but you could clone your new form to that other form that is already embedded by using Field Manager app, so you will be able to keep the same URL for your new form.
Or you just embed new form into your website.
