It's doing it on all of the pages that try talking to the databas that was made by the Web Assist products.
For instance when trying to insert a new product on insert.php it's referring to these line codes.
$MM_editCmd = mysql_query($WA_Sql, $WA_connection) or die(mysql_error());
product results: Undefined variable: totalRows_WADAproducts with code
$queryString_WADAproducts = sprintf("&totalRows_WADAproducts=%d%s", $totalRows_WADAproducts, $queryString_WADAproducts);
and also mysql_select_db() expects parameter 2 to be resource, object given with two lines of code
$WADAproducts = mysql_query($query_limit_WADAproducts, $Summit) or die(mysql_error());
also with the products_results.php page.
