X-Cart forums - cart.php question

I added a <div> just before the </body> tag in skin1/customer/home.tpl.
This adds a footer that spans the entire screen on my product pages, search pages, basically every page but cart.php

Can you tell me what where cart.php is getting its </body> tag from?

One of the last lines in the root folder 'cart.php' file is:

HTML Code:

func_display("customer/home.tpl", $smarty);

I assumed this is pulling the same home.tpl page, but like I said the <div> isn't there.

***EDIT***

This only happens when the cart has an item in it. When it is empty, it looks fine. Maybe this has something to do with the cart page only having 1 column when full, but 2 cols when empty.
Has anyone encountered this before?
