oops! Help with Header - PLEASE

[chachab]

The following is what i am trying to change .. i tried with the "new products section.. didnt work.. then i tried to put it back and its not working - so something there is screwed up...

what i am trying to do is enter my ABOUT US page in place of the New Products page and link on my header. Once i learn how to do this.. I can add a links page or a FAQ page instead of "specials"

Can someone PLEASE look at my code below and help me?
i tried doing it by direction of tutorial.. didnt work.. then i went here..
includes / templates / 1112 / common / tpl_header.php

<td><?php echo zen_image($template->get_template_dir('/menu_s.gif', DIR_WS_TEMPLATE, $current_page_base,'images'). '/menu_s.gif', '') ?></td>
<td<?php echo ($current_page_base == FILENAME_NEW_PRODUCTS) ? ' class="current"' : ''; ?>><div><div><div><a href="<?php echo zen_href_link(FILENAME_NEW_PRODUCTS, '', 'NONSSL'); ?>"><?php echo PRODUCTS_NEW; ?></a></div></div></div></td>
<td><?php echo zen_image($template->get_template_dir('/menu_s.gif', DIR_WS_TEMPLATE, $current_page_base,'images'). '/menu_s.gif', '') ?></td>
<td<?php echo ($current_page_base == FILENAME_SPECIALS) ? ' class="current"' : ''; ?>><div><div><div><a href="<?php echo zen_href_link(FILENAME_SPECIALS, '', 'NONSSL'); ?>"><?php echo BOX_HEADING_SPECIALS; ?></a></div></div></div></td>
