$numItem = count($itemQty);
$numDeleted = 0;
$notice = '';

$sql = "SELECT pd_name, pd_qty
FROM tbl_product
WHERE pd_id = {$productId[$i]}";
$result = dbQuery($sql);
$row = dbFetchAssoc($result);
if ($newQty > $row['pd_qty']) {
// we only have this much in stock
$newQty = $row['pd_qty'];
// if the customer put more than
// we have in stock, give a notice
