That's ... odd. "Error: No forum selected" can only occur when no forum variable was passed in to the script. Unless your Javascript is doing something silly like cutting off the query string at some point (which I doubt, as that would cause other noticible effects), it's highly unlikely that it's the primary cause of the problem.

Have you considered running without the frameset Javascript, and instead using a frame detection script, such as the one used at QuirksMode? Try visiting this page and notice the "This page is supposed to be in a frameset" link at the top. The page also explains how that link works. <img src="https://www.ubbcentral.com/boards/images/graemlins/wink.gif" alt="" />
