cart "continue shopping" button problem

[Guest]

Hi,

 

im having a problem with the shopping cart:

 

i'd like to change he navigation of the button " continue shopping" in the checkout process, i want it to go back 3 pages, by changing the attribute to -3, (or to just redirect it to >cataloge>index all together, i read the threads on doing this, but i can't find the codes in the >catalog>shopping_cart.php

 

mine just looks like this:

 

<?php

/*

$Id: shopping_cart.php,v 1.73 2003/06/09 23:03:56 hpdl Exp $

require("includes/application_top.php");

 

require(DIR_WS_LANGUAGES . $language . '/' . FILENAME_SHOPPING_CART);

 

$breadcrumb->add(NAVBAR_TITLE, tep_href_link(FILENAME_SHOPPING_CART));

 

$content = CONTENT_SHOPPING_CART;

 

require(DIR_WS_TEMPLATES . TEMPLATENAME_MAIN_PAGE);

 

require(DIR_WS_INCLUDES . 'application_bottom.php');

?>

 

i did install the BTS and several other mods though... can anyone tell me whats wrong and were i can find the codes to change the behavior of the CONTINUE SHOPPING button?
