Hey guys...I can't figure this out..

I need to make this popup window image link point to the window behind itself...I keep trying to find these remote scripts but all of them have scripts that start with a window.open function and I already have that programmed...I need just the script to make the links within the popup to change the "main" browser window beneath. Here's a link to the site I'm trying to make this happen at. When the popup window comes up I need the "Order Now" graphic link to change the background main window to the order page....how is this done...I'm going nuts!! Check out my scripts within the main window at:

the "order now" link is within the popup window on the first page that comes up: index.html

THanks for any help!!!
