problem solved

1. Open includes/languages/english/product_info.php
and add:
define('TEXT_XSELL_PRODUCTS', 'We Also Recommend :');
just above the final ?>

2. Open includes/templates/template_default/templates/tpl_product_info_display.php and insert the following code
<?php require($template->get_template_dir('tpl_modules_xsell_products.php', DIR_WS_TEMPLATE, $current_page_base,'templates'). '/' . 'tpl_modules_xsell_products.php');
?>
I have a little request

looks a little messy, if it can add a box to separate these 2 sections will be more easy to see.
