Thanks,

I can't seem to get this to work, either.

Should it look like this?

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

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

How are other people who run UBB Threads adding self run banner ads to their site if PHP doesn't work? Javascript/SSI, Perl?

Please help, I have a customer who paid for this already and I want to fulfill.

Thanks in advance.
