What I'm trying to do is so that if Type of admin is selected to Full admin, then the final price will have 10 dollars added.

 

Thank you

[RussellReal]

if ($_POST['on1'] == 'Full admin + $10.00') {

  $total_price += 10;

}

Hi, thanks for the response, but I don't know where to put that.

 

Here is my current code.

 

<?php
$submit_y = $_POST["submit_y"];
if(!$submit_y){
