UBB.threads PHP Forum Software Community Forums UBB.threads 6 Version 6 Support PHP code in UBB Threads

Hi,

I'm trying to install a banner rotating program on my UBB Threads forum and can't seem to get it to work.

I'm basically adding this code to my forum header:

<?
require "ad.php";
$advertisement = show_ad();

// page shows something here
echo $advertisement // the banner appears
?>

Can someone point me in the right direction to get this script to work? It works on the main site, but not on the UBB Threads forum.

Thanks in advance.
