Hello Andrew,

The code looks right, but I would ensure you are receiving exactly what you are expecting to receive. I would suggest utilizing the following code to verify what is being passed during form processing:

echo "<pre>";
      echo "POST data: <br/>";
     print_r($_POST);
     echo "<br/><br/>GET data: </br/>";
     print_r($_GET);
echo "</pre>";

I suspect the GET data isn't coming through as suspected. Please post the results and I can assist with troubleshooting further.

Thanks and good luck,

Zac

Thanks for the help but I already had help from my friend. Turned out to be exiting the code every time it didn't work. Thanks again!
