Cross selling mod taking away right sideboxes

I added the following addon

http://www.zen-cart.com/index.php?ma...products_id=76

Step 5 on the install instructions say:
5. Now edit your product-info template file (includes/templates/templates_default/templates/tpl_product_info_display.php) and insert the following code
at the point where you wish the Cross-Sell box to appear. Usually best at the end of the file:

<?php require($template->get_template_dir('tpl_modules_xsell_products.php', DIR_WS_TEMPLATE, $current_page_base,'templates'). '/' . 'tpl_modules_xsell_products.php'); ?>

I've tried adding this is several places in the tpl_product_info_display.php but where ever I add it when I refresh my page the cross products don't show up and it takes the sideboxes on the right side away. Here's the end of my tpl_product_info_display.php sheet. What am I doing wrong/where should I be putting this? Thanks so much

here's what the tpl_product_infophp looks like with the code where I've entered it. At the bottom "Cross sell information"

Here's a link to the product page

As you can see the cross sell box deosn't show up and takes away the right side boxes. any thoughts on how to fix this?
