error on count()

hello, this is problably newbie question, but I can not understand why my count() function doesn't work. I need to count how many items has a determinated customer ordered ever. 1. I tired to get the array like this: $una = $check["uname"]; function orderquantity ($una) { $pss = mysql_query("SELECT OID FROM orders WHERE una = '".trim($una)."'") or die (mysql_error("Query error on Order search")); while($pisao=mysql_fetch_array($pss)) { return count($pisao); } } $okuan = orderquantity(); 2. and like this: $una = $check["uname"]; function orderquantity ($una) { $pss = mysql_query("SELECT OID FROM orders WHERE una = '".trim($una)."'") or die (mysql_error("Query error on Order search")); return count($pss); } okuan = orderquantity(); None of them gave me a valid value, is it because the OID is an int value? --------------------------------- Créez gratuitement votre Yahoo!
