Hi Leon,

sorry it's taken a few days to get back to you.

The use of SEF URLs won't actually change whether $id is populated. It still gets populated - it's a kind of magic!

Can you describe a little more the way that your categories and pages are set up, and which ones you want the slideshows to appear on or not appear on?

e.g. are there a fxed number of top level categories that you want the slideshow to appear on, and not appear on any other pages on the site?

If that's the case, then you could probably do something like this:

$vm = JomGenius("virtuemart");
if ($vm->check("category_id = 4, 5, 6, 10") and $vm=>check("pagetype = category")) return XXX;
// replace XXX with the module id to display on those categories
// replace 3, 4, 6, 10 with any list of the category ids on which to display the module.


Cheers,
Stephen
