Wordpress Themes - WP Forum at BFA - Help! Trying to combine e-commerce navigation and page menu bar together??

HTML Code:

<ul>

        <?php shopp('catalog','category-list','wraplist=no&hierarchy=true'); ?>

</ul>

and I am trying to figure out where/what file in the theme to place this in to combine my page menu bar and their category menu. Basically, they indicate that the code above will :

This example shows how to "merge" the WordPress pages navigation menu with the Shopp categories menu.

I just am not sure which Atahualpa file to place this into, and where in that file, in order to get it working.

Thanks!!!!
