Mine doesn't look quite like that,
This is what my file looked like..
$WADbSearch1->whereClause .= " AND ProductID IN (SELECT ProductID FROM ps3_productcategories WHERE (CategoryID = ".implode($_GET["ProductCategoryID"]," OR CategoryID = ")."))";
} else {
$WADbSearch1->whereClause .= " WHERE ProductID IN (SELECT ProductID FROM ps3_productcategories WHERE (CategoryID = ".implode($_GET["ProductCategoryID"]," OR CategoryID = ")."))";
There's two searches like the one you said to change...and they're not on line 84.
I honestly don't think is has anything to do with the product results page. It's the same page straight from the PS3 download folder and it works on all of our other sites. Is there anything else that could be wrong?
