Problems showing tab content

[Star7]

Script: DD Tab Menu
http://www.dynamicdrive.com/dynamicindex1/ddtabmenu.htm

Hi everyone, I've just started designing a website for my psychology project.

However, everything is working fine except that the tab content is not showing.

Here's the codes:

<div id="ddtabs" class="glowingtabs">
<ul>
<li><a href="http://www.dynamicdrive.com" rel="gc1"><span>Home</span></a></li>
<li><a href="http://www.dynamicdrive.com/new.htm" rel="gc2"><span>What</span></a></li>
<li><a href="http://www.dynamicdrive.com/style/" rel="gc3"><span>How</span></a></li>
<li><a href="http://www.dynamicdrive.com/forums/"><span>References</span></a></li>
<li><a href="http://tools.dynamicdrive.com/imageoptimizer/"><span>Links</span></a></li>
</ul>
</div>

<DIV class="tabcontainer">

<div id="gc1" class="tabcontent">
Return to the <a href="http://www.dynamicdrive.com">frontpage</a> of Dynamic Drive.
</div>

<div id="gc2" class="tabcontent">
See the new scripts recently added to Dynamic Drive. <a href="http://www.dynamicdrive.com/new.htm">Click here</a>.
</div>

<div id="gc3" class="tabcontent">
Original, practical <a href="http://www.dynamicdrive.com/style/">CSS codes and examples</a> such as CSS menus for your site.
</div>

</DIV>

I'm not really sure what is wrong.

Btw, the site is not online yet, if you really need more details, I've attached the problematic file.

Specifically, its the "The Pulfrich Effect.dwt" under the template folder.

All help appreciated. :D

Is it possible to post a temporary page online of the problem? It's generally much easier to debug online, and also, some issues that don't show up offline do when viewed online, such as problems with paths.
