Presently, I have linked categories on the top and left sidebar (which will stay) of my page. I need to replace the linked categories at the top and replace them with a mission statement and can't find this file in e-z pages or layout controller. A sample source code is below (thank you for your help):

<div id="navCatTabsWrapper">
<div id="navCatTabs">
<ul>
<li><a class="category-top" href="http://www.northeastjanitorial.com/janitorial_supplies/index.php?main_page=index&amp;cPath=56">Air movers, Air filters and Fans</a> </li>
