Problem with banner not showing up on certain pages

[frank44]

We have a simple banner rotation script running, but the banner doesn't show up on certain pages? It shows up on the home page and when you click today's posts, but not on the general forum link?


Here is the script we are running on the header

<SCRIPT language=JavaScript>
