checkout problem

For some strange reason, the cart seem to be stuck on step 2 during the checkout process, i am using paypal and it does not go onto step 3

Do you have your paypal module restricted to certain zones?
what payment options are showingon your checkout-payment page ?

just paypal showing by itself, but i think the problem lies with the advertizing tracker and the insert which you have to put in
"In includes\modules\pages\checkout_confirmation\header_php.php

Find:

$_SESSION['comments'] = zen_db_prepare_input($_POST['comments']);

Below this line add:

// BEGIN ADDITIONS - if no advertizer has been selected, show an error and force them to select where they saw our ad - JTD
  $_SESSION['advertizers'] = zen_db_prepare_input($_POST['advertizers']);
// Note: If you don't want to force customers to make a selection, simply comment out the next two lines of code...
  if ($_SESSION['advertizers'] == NULL)
      $messageStack->add_session('checkout_payment', ERROR_NO_ADVERTIZER_SELECTED, 'error');
// END ADDITIONS - JTD" 

This causes some problem as when i remove this from the header, my checkout works.
