als ik van alles 1 neem dan klopt de prijsberekening wel maar van zodra ik de aantallen ga vermeerderen klopt de prijsberekening niet meer wat doe ik verkeerd?
stukje gerelateerde code
echo "Items ordered: ".$totalqty."<br />\n";
echo "Subtotal: $".$totalamount."<br />\n";
$taxrate =0.10; //local salestax is 10%
$totalamount = $totalamount + ($totalamount * $taxrate);
$totalamount=number_format($totalamount, 2);
echo "Total including tax: $".$totalamount."<br />\n";
echo "<p>Address to ship to is ".$address."</p>";
