Tabbed Contents

I have a default.asp page that is tab driven.  This is going to be a database front end.  I want to build the content of each tab in a seperate page.   How can i make the content of each tab display an external page?  Please note that i seem to have great difficulty referencing nested elements. Here is the tab code i used, excluding the external script source.

<link rel="stylesheet" type="text/css" href="tabcontent.css" />

<script type="text/javascript" src="tabcontent.js">

        <ul id="menutabs" class="shadetabs">
        <li><a href="#" rel="taboption1" class="selected">Start Page</a></li>
        <li><a href="#" rel="taboption2">Standards Explorer</a></li>
        <li><a href="#" rel="taboption3">Policy Editor</a></li>
        <li><a href="#" rel="taboption4">Proof Editor</a></li>
        <li><a href="#" rel="taboption5">Reports</a></li>
        <li><a href="#" rel="taboption6">Utilities</a></li>
        <li><a href="#" rel="taboption7">Trouble Tickets</a></li>
        </ul>

        <div style="border:1px solid gray; width:875px; margin-bottom: 1em; padding: 10px">

        <div id="taboption1" class="tabcontent">
        Tab content 1 here<br />Tab content 1 here<br />
        </div>

        <div id="taboption2" class="tabcontent">
        Tab content 2 here<br />Tab content 2 here<br />
        </div>

        <div id="taboption3" class="tabcontent">
        Tab content 3 here<br />Tab content 3 here<br />
        </div>

        <div id="taboption4" class="tabcontent">
        Tab content 4 here<br />Tab content 4 here<br />
        </div>
       
        <div id="taboption5" class="tabcontent">
        Tab content 5 here<br />Tab content 5 here<br />
        </div>
       
        <div id="taboption6" class="tabcontent">
        Tab content 6 here<br />Tab content 6 here<br />
        </div>
       
        <div id="taboption7" class="tabcontent">
        Tab content 7 here<br />Tab content 7 here<br />
        </div>
        </div>

        <script type="text/javascript">

        var taboptions=new ddtabcontent("menutabs")
        taboptions.setpersist(true)
        taboptions.setselectedClassTarget("link") //"link" or "linkparent"
        taboptions.init()

        </script>
