if you can switch to the classic template you will find that this link by default is along this line:
Code:
http://www.your_domain.com/index.php?main_page=contact_us
so where you have your ul as:
Code:
<ul class="back"> <li><?php echo '<a href="' . HTTP_SERVER . DIR_WS_CATALOG . '">'; ?><?php echo HEADER_TITLE_CATALOG; ?></a></li> <?php
require($template->get_template_dir('tpl_modules_categories_tabs.php',DIR_WS_TEMPLATE, $current_page_base,'templates'). '/tpl_modules_categories_tabs.php'); ?> <?php
require($template->get_template_dir('tpl_ezpages_bar_header.php',DIR_WS_TEMPLATE, $current_page_base,'templates'). '/tpl_ezpages_bar_header.php'); ?> <?php
require($template->get_template_dir('tpl_contact_us_link_header.php',DIR_WS_TEMPLATE, $current_page_base,'templates'). '/tpl_contact_us_link_header.php'); ?> </ul>
I would replace that with:
Code:
<li><a href="http://www.your_domain.com/index.php?main_page=contact_us''>Contact Us</a>;
</ul>
