darren@microcyb.com - the best way to resolve your problem would be to do this: $query = "SELECT count(subid) as count, subid FROM table GROUP BY subid"; $result = mysql_query($query); based on the following data this would return: id subid url urlname 1 2 yahoo.com yahoo 2 2 google.com google 3 1 myserver.com server 4 2 anotherserver.com server +-------+-------+ | count | subid | +-------+-------+ | 3 | 2 | | 1 | 1 | +-------+-------+ it's also a lot less database-intensive to do it this way - using COUNT() instead of mysql_num_rows. -- http://www.php.net/manual/en/function.mysql-num-rows.php http://master.php.net/manage/user-notes.php?action=edit+21139 http://master.php.net/manage/user-notes.php?action=delete+21139 http://master.php.net/manage/user-notes.php?action=reject+21139
