How to remove a tab from Accordion Menu?

Question

I have a page that I am creating for my website which has an accordion menu on it.  I originally created the menu in Dreamweaver CS4 using the Spry Accordion Widget, then transferred that code over to the website page.  In place of words on the menu, I am using images for each drop down tab.  I am trying to remove the last tab in the menu, but every time I do my entire menu no longer functions and the tabs, when clicked, no longer drop down.

Above is the link to the page I am working on.  The last tab in the menu is titled TOC Thinking Processes (above the Register Now button).  All I want to do is remove that tab, but when I do, the entire menu no longer works.
Please let me know if you need anything else from me.

Answer 1

Never mind, I was able to figure it out.  After I had removed lines 631-644 the code had changed for some reason.
CHANGED FROM THIS:
<script type="text/javascript" class="AccordionPanelClosed">
//<![CDATA[
<!--
var Accordion1 = new Spry.Widget.Accordion("Accordion1");
//-->
//]]>
</script><br>
TO THIS:
<div class="AccordionPanel AccordionPanelClosed">
//<!--[CDATA[
<!--
var Accordion1 = new Spry.Widget.Accordion("Accordion1");
//---->
//]]&gt;
<br>
Turns out I was just missing the <script type="text/javascript" class="AccordionPanelClosed"> to match up with the </script> code at the end.  Thanks for your help!
