I assume worldsbestsynthetics.com/worldsbestsynthetics/ is the page in question. Try disabling the 4th menu bar on you page:

<script type="text/javascript">
ddlevelsmenu.setup("ddtopmenubar", "topbar") 

//ddlevelsmenu.setup("mainmenuid", "topbar|sidebar")
ddlevelsmenu.setup("ddtopmenubar1", "topbar") 

//ddlevelsmenu.setup("mainmenuid", "topbar|sidebar")
ddlevelsmenu.setup("ddtopmenubar2", "topbar") 

//ddlevelsmenu.setup("mainmenuid", "topbar|sidebar")
ddlevelsmenu.setup("ddtopmenubar3", "topbar") 

//ddlevelsmenu.setup("mainmenuid", "topbar|sidebar")
//ddlevelsmenu.setup("ddtopmenubar4", "topbar") 

//ddlevelsmenu.setup("mainmenuid", "topbar|sidebar")
</script>

Notice the "//" proceeding the 4th menu bar code above, to disable it. I suspect that's the culprit, since "ddtopmenubar4" references a SPAN on your page, instead of the required UL element.

BTW, please note that your page is currently in violation of our usage terms, since the credit notice doesn't appear inline on the page. Please reinstate the credit notice: http://www.dynamicdrive.com/notice.htm

Thanks for the reply. I have added the credit notice to the script tags directly on the page. Unfortunately disabling that menubar did not resolve the issue, just disabled the dropdown. Also tried changing from span to ul id but no luck there either. Any further suggestions would be appreciated. The page can be accessed directly at http:worldsbestsynthetics.com/test.shtml

By process of elimination I fixed the error by disabling the ddtopmenubar3.
//ddlevelsmenu.setup("mainmenuid", "topbar|sidebar")
//ddlevelsmenu.setup("ddtopmenubar3", "topbar")

I still can't find what is causing the error. The code for ddtopmenubar3 is:

<tr>
          <td class="navbrder bgnav"><table align="center">
              <tr>
                <td>
                  <ul style="margin:0" id="ddtopmenubar3" class="mattblackmenu ver11white">
                   <li><a href="http://worldsbestsynthetics.com/oil-testing.shtml" class="ver11white" rel="ddsubmenu27">Oil Analysis</a></li>
                   <li><a href="https://www.amsoil.com/company.aspx?zo=1607375" class="ver11white" rel="ddsubmenu28">Amsoil info</a></li>
                   <li><a href="https://www.amsoil.com/techservices.aspx?zo=1607375" class="ver11white" rel="ddsubmenu29">Ask Amsoil </a></li>
                    <li><a href="http://www.worldsbestsynthetics.com/lit/interval_change_guide_g1490.pdf" class="ver11white" rel="ddsubmenu30">Oil Change Interval Guide</a></li>
                  </ul></td>
              </tr> 
            </table></td>
        </tr>

I would like to find the problem, so I can expand these menus in the future. Any help is greatly appreciated.
Thanks,

A problem, perhaps the problem, as I've seen this sort of thing many times, is that there are no corresponding drop downs for those rel attributes. For example, where you have:

<a href="http://worldsbestsynthetics.com/oil-testing.shtml" class="ver11white" rel="ddsubmenu27">

This tells the script to look for an element with the id of 'ddsubmenu27', none exists, so it throws an error. The same is true of ddsubmenu28, ddsubmenu29, and ddsubmenu30.

So, you either need to make those, or remove the rel attributes. If you choose to remove them all, may as well not init that submenu group.

[jsroessler]

The error was because I had not specified the individual ddsubmenu items. The Proper code was:

<tr>
<td class="navbrder bgnav"><table align="center">
<tr>
<td><ul id="ddsubmenu26" class="ddsubmenustyle">
<li class="bder"><a href="#" onclick="aFunction();return false;">ALL</a></li></ul>
<ul id="ddsubmenu27" class="ddsubmenustyle">
<li class="bder"><a href="#" onclick="aFunction();return false;">ALL</a></li></ul>
<ul id="ddsubmenu28" class="ddsubmenustyle">
<li class="bder"><a href="#" onclick="aFunction();return false;">ALL</a></li></ul>
<ul id="ddsubmenu29" class="ddsubmenustyle">
<li class="bder"><a href="#" onclick="aFunction();return false;">ALL</a></li>
</ul>
<ul style="margin:0" id="ddtopmenubar3" class="mattblackmenu ver11white">
<li><a href="http://worldsbestsynthetics.com/oil-testing.shtml" class="ver11white" rel="ddsubmenu26">Oil Analysis</a></li>
<li><a href="https://www.amsoil.com/company.aspx?zo=1607375" class="ver11white" rel="ddsubmenu27">Amsoil info</a></li>
<li><a href="https://www.amsoil.com/techservices.aspx?zo=1607375" class="ver11white" rel="ddsubmenu28">Ask Amsoil </a></li>
<li><a href="http://www.worldsbestsynthetics.com/lit/interval_change_guide_g1490.pdf" class="ver11white" rel="ddsubmenu29">Oil Change Interval Guide</a></li>
</ul></td>
</tr>
</table></td>
</tr>

It is working fine now, Thank you for the info on where to look. Much appreciated.

[jsroessler]

Just what I found. Added the corresponding menus and just like magic it was fixed. Thanks!
