thank you page needs to stay up longer

Is there any way to make the thank you page stay available for viewing longer ? the client needs to get the order number off of this page since a call center is using the cart not the customer

using authorize.net AIM

posted in wrong section, moved to the HOW to section

Why not just remove the URL in the "return URL" option of the authorize.net plugin's options screen ? That will remove the redirection and the user will have all the time he wants to get the order number of that page.

removed the re-direct to the page but still stays up for just a second but the cool thing is that it does go to the thank you page now

I tried slipping the order number in that code but get this error message on the page

Notice: Undefined variable: vars in /home/parts/public_html/rmgsilver/templates/gk_twn2/html/com_hikashop/checkout/after_end.php on line 13
Order number:

here is what i did

<?php

defined('_JEXEC') or die('Restricted access');
?>
<?php
$app =& JFactory::getApplication();
$app->enqueueMessage( JText::_('THANK_YOU_FOR_PURCHASE') );echo ' Order number: '.$vars;

as usual you guys rock

There, you should use $this->order->order_number instead of $vars

got it Nickolas thanks again
