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.
The form in this page: http://www.roommategroup.com/room-wanted-form-2.html is embedded using our iframe method, but it's still cut off at the bottom. That is related to your form container or the html block that currently holds the form. You need to adjust it in your current website builder. Here's a screenshot for example:
As you could see, your container height is just 4000+ px, but your form is 7000+. Please adjust that. Otherwise, your users can't submit the form.
