Nice menu problems

All, 
 
I have been testing struts-menu with the "nice-tabs" templates based upon
the demo. 
 
I've just about got it working, but the formatting is off and I can not
figure out why. 
 
You can see the current state of my test in the following screen shots:

www.scoutingplanet.com/download/sm-2.gif (Firefox)
 
Notice that both are off, but differently in different browsers. 
 
In IE, there is also a javascript error that states:
 
Error: "null" is null or not an object
 
No exceptions are being thrown.
 
When I click on one of the nice tabs, I now revert to a unordered list type
of format.

The menus portion of my menu-config.xml is:
    <Menus>    
        <Menu name="Home" title="Home" location="?Home" target="_blank" />
        <Menu name="News" title="News" location="?News" target="_blank" />
        <Menu name="Calendar" title="Calendar" location="?Calendar"
target="_blank" />
        <Menu name="Tools" title="Tools"  >
            <Item name="MBCounselorLookup" title="MB Counselor Lookup"
location="?MBCounselorLookup"/>
            <Item name="faqs" title="FAQ's" location="?faqs"/>
            <Item name="scoutlinks" title="Scouting Links"
location="?scoutlinks"/>
        </Menu>
    </Menus>
 
Any pointers to what I am doing wrong would be greatly appreciated. 
 
Thank you.
