$totalamount = ($tireqty * TIREPRICE + $oilqty * OILPRICE + $sparkqty * SPARKPRICE) * (1+$discount);
echo "Subtotal (Discount applied here): $".number_format($totalamount, 2)."<br />";
$taxrate = 0.10;
$totalamount = $totalamount * (1+ $taxrate);
echo "Total including Tax: $".number_format($totalamount,2)."<br />";
}
?>
Any help would be appreciated.

Answer 1

I am a beginner so I might wrong but here elseif ($tireqty >= 10) && ($tireqty <= 49) I would use and extra bracket:
elseif (($tireqty >= 10) && ($tireqty <= 49)) {
...
}
Hope this is it:)

Answer 2

This is a terrible question but here goes... without knowing what's "not working" I can only guess:
i f ($totalqty == 0) {
That's a syntax error. You probably meant:
if ($totalqty == 0) {
Likewise, here:
if ($tireqty < 10) {
$discount = 0;
}
elseif ($tireqty >= 10) && ($tireqty <= 49) {
$discount = 0.05;
}
elseif ($tireqty >= 50) && ($tireqty <= 99) {
$discount = 0.10;
}
elseif ($tireqty >= 100) {
$discount = 0.15;
}
The entire conditions need to be enclosed in parens:
elseif (($tireqty >= 10) && ($tireqty <= 49)) {
$discount = 0.05;
}
elseif (($tireqty >= 50) && ($tireqty <= 99)) {
$discount = 0.10;
}
elseif ($tireqty >= 100) {
$discount = 0.15;
}
It's possible there's a lot more things wrong here. Please edit your question and describe specifically what is not working, and what you've done to fix it, and what you need help with.
