The problem is as the error says, totalqty is not the name of one of your
form elements, I think infact you want:
echo "Items ordered: " . $totalqty . "<br>\n";
Since the $_POST is just used to read varibles sent to you from a form,
whereas any other varibles you make ie:
$totalqty = $_POST["tireqty"] + $_POST["oilqty"] + $_POST["sparkqty"];
Can just be referenced with $totalqty (no need for the $_POST)
I hope you understand the different, and that your error was just a typing
mistake..
Happy Coding
Andrew
