if(($r = mysql_fetch_row($res)) >=1)if($r = mysql_fetch_row($res)) will work fine if you only have one row being returned. If you have more than one that you need to loop through, then: if($r = mysql_fetch_row($res)) { do { }while($r = mysql_fetch_row($res)); } Now you have the added efficiency of not having to call mysql_num_rows() (if you don't need that value). -- ---John Holmes...
