iframe and form submit issue

I need a script that will do the following: 1. Load a page (1) in an iframe 1x1 pixel. 2. Load a page (2) in an iframe that is full screen. 3. Website visitor enters information in a form on page (1). 4. Visitor presses submit on form on page (1). 5. Page (1) form values are populated in page (2) form and submitted through page (2). If this is not the way to go about doing this, possibly: 1. Create an iframe of just the form zone of page (1) and put it on page (2) so it looks like it's part of that page. Basically I'm just trying to customize a landing page and get the form fill-outs to be submitted through another landing page. The original form page (1) is not mine, so I cannot format any code on this page.
