Flash Banner onclick to Flash Overlay?

Hi all :D:

Hope you’re well. I was hoping someone could lend some insight to my current dilemma?

I’m attempting to create a flash ad banner (728x90 leaderboard) which, when clicked on, loads a new frame that expands to fill the view port with a 6 page flash form.

I’m not sure how I would go about loading a whole new window off of a banner which has already been predefined to a stage size of 728x90.
I understand that if it were an expandable - I could merely make the stage larger, and knock out the transparency within the html/css.

I’m pretty stumped :\ I really appreciate any help anyone could lend on the matter. Here’s an example of what I’m trying to do, but it was done with css/js, http://tinyurl.com/32o3oae(Click on the top banner).

Thank you!
