Validating php form

I was wondering if anyone can give me a hand here. I'm using a pre-made php form from simplemodal. The problem I'm facing is the form always returns me with the "Unfortunately, your message could not be verified." error, which is echoed out by this php loop.

// make sure the token matches
      if ($token === smcf_token($to)) {
            smcf_send($name, $email, $subject, $message, $cc);
            echo "Your message was successfully sent.";
      }
      else {
            echo "Unfortunately, your message could not be verified.";
      }

Either that or it just goes straight to this error:       die("Unfortunately, a server issue prevented delivery of your message.");

The link for the form is http://www.arjaywireless.com/Temp/contact/index.html
I've also attached the contact.php file which is used to run and validate the form.

Thanks in advance.
