AsianPay Payment Module Implementation Problem

[marijuana]

Hello,
I am trying to implement a payment module, the problem I am having is that whatever happens in the transaction page I receive a message that says my transaction was successful but in reality it was supposed to say transaction failed, because I am entering wrong CC info.

function before_process() {
      global $_POST, $messageStack;

    if ($_POST['Succeed'] == '0') return;
    if ($_POST['Succeed'] == '1') {
      $messageStack->add_session('checkout_payment', MODULE_PAYMENT_ASIANPAY_TEXT_DECLINED_MESSAGE, 'error');
      zen_redirect(zen_href_link(FILENAME_CHECKOUT_PAYMENT, '', 'SSL', true, false));
    }
    // Code 3 is an error - but anything else is an error too (IMHO)
    $messageStack->add_session('checkout_payment', MODULE_PAYMENT_ASIANPAY_TEXT_ERROR_MESSAGE, 'error');
    zen_redirect(zen_href_link(FILENAME_CHECKOUT_PAYMENT, '', 'SSL', true, false));
    } 

Above code is in the payment module page and it is invoked in includes/modules/checkout_process.php as below

// load the before_process function from the payment modules
$payment_modules->before_process(); 

This code does not seem to work properly. Somehow the system bypasses before_process() function. Where do I make mistake? Could anyone help me please? Thank you.
