Thanks, but I think the update function should be built in -- the sql checks whether the userAnswer table contains the q_id the user has just entered; if so, it deletes the row containing it and then the second query inserts the new values. $qidlist_sql="DELETE FROM teresa WHERE q_id IN (" . (implode(",",$qidlist)) . ");" $q_a_sql="INSERT INTO teresa (u_id, q_id, a_id )

                VALUES " . (implode(",",$qanda)) . ";";

I think there's something wrong with the logic of how I'm handling $_POST info and passing it back and forth: here's why: if I close the browser and reopen it and refill the same questions, the answer table shows the updated answers. there's something in the logic I am using about how I am advancing the $cat and managing the $_POST information. I think . But I cannot find it. Anyone?
