I can't make the calculator to whom I can submit numbers , and it will make the calculation ,
So far I wrote this script, but it doesn't work.
Can someone tell me where am I wrong??????
<?
$a=$POST['numer1'];
$b=$POST['numer2'];
$c=$POST['operator'];
$d=$POST['equall'];
$rez="";
if(isset($d)) {
switch($c) {
case "+":
$rez = ($a + $b);
break;
case "-":
$rez = ($a - $b);
break;
case "*":
$rez = ($a * $b);
break;
case "/":
$rez = ($a / $b);
break;
}
}
?>
