I have messed with this for a couple of days and cant get it right. Maybe I need sleep :-) The code below is echoing the qty correctly (10, 5, 25) for ($i = 1; $i <= $sendnum; $i++) {
            $qty = $_POST['qty'.$i];
            echo $qty . '<br />';
} The question is, how would I take add each of these numbers (10+5+25)?

$sum = 0 // init the var for ($i = 1; $i <= $sendnum; $i++) {

    $sum =+ intval($_POST['qty'.$i]);

} echo "$sum<br />";

Any help is appreciated.
