Whoops. I said the wrong thing. It appears all the header tags work correctly on the product_info.php page, I was just not editing the right fields. However, the problem is with the Header Tags Category Title, Header Tags Category Description, and the Header Tags Category Keywords on the categories page (you know the index.ph?(dah dah...)). If I add the tags to the index.php page, then those tags appear on all categories pages, and if it left empty, they are empty. Some help on this would be much appreciated. BTW, this is an amazing contribution, worthy of a medal!!!
