iFrame embedded multi-page form is very long

I'm using mutiple pages, but now the form in my website is very long (i doesn't stop atfer the pagebreak). How to fix this?

I can see the issue issue.

You are using the iFrame embed method to avoid scripting conflict between the form and JQuery on your page. Unfortunately, the iFrame doesn't have an interactively changeable height, so the height of the iFrame must be set to be long enough to contain the longest page of the multiple page form.

As some of the pages are short, it appears that there is a lot of empty space at the bottom of these short pages, but unfortunately we can't avoid this.Please let us know if we can be of further assistance.
