Button links in frames

im making this new site for a friends band. the site has a top and left side frame. in the left side is a flash menu with several buttons. i cant figure out how to get the buttons to open up the page in the mainframe.

as u can see (press tour) i can only get the page to open up in the whole window.

this is the only thing holding me back from fishing this site, so all help is appreciated. please ask if u need more information. thanks in advance.
