In need of simple script

I want to create a link in the adbar of my redirection service that will destroy the ad frame. The frameset consists of 3 rows, the main one, the banner frame, and an invisible frame on the bottom. I want to have the link replace the current page being viewed in the main window and the adframe with the current page in the main window without touching the bottom invisible frame. Is there any way of doing this? If not, I would just like a script that would load the current page being viewed in the main frame into _top.
