Darkwander the dvd sql in your download file link a few posts back does not have those fields mentioned in it I think.....

So you need to search for 'products p, products_description pd' in your other code areas in admin files and see what goes on, presumably its a collect_info.php admin page for your selected/ edited product type

its either before it, which is probably a 'select' something,
or after, in which case a field name or syntax comma is wrong

I usually show the sql instruction by 'echo' at the faulty place
to show it on the page, its then obvious, but sometimes it needs the code rearranging to get at the sql statement itself as a 'printable' item

hope this helps rather than hinders
