I have a table which contains items which people want to buy. It is based on the session ID so that they can be retrieved for the cart. However, I want the quantity to change the amount of postage. This is the code i have written so far: $sid = session_id(); $sql = "SELECT SUM(ct_qty) FROM tbl_cart WHERE ct_session_id = '$sid'"; $result = dbQuery($sql); $totalquantity = $result; echo $totalquantity; However, this just echos 'Resource id #14'. I want the code to add up all the ct_qty values where the ct_session_id is equal to $sid. I am new to this more advanced coding so any help would be appreciated. Thanks in advance. Imateacher
