rotating banners

[elvis_is_dead]

I'm having trouble getting a php rotating banner script running on our forums. The script itself can be seen at:
http://www.derbytrail.com/ads/rotate/rotate.php ... center ad is swopping out

But I can't get the script itself to run on the actual forum pages. I've placed the code below into the header using the style manager ...

ideas anyone??
