Firefox 2 throws an error, but IE 6 works fine


My first jQuery project has me puzzled. I have a page
http://twinflamingos.com/chris/chris.htm that throws and error when
any of the menu headers is clicked. In IE 6 the drop-down works
perfectly, but FF 2 doesn't work and puts an error in the log.
Specifically it says:
Error: [Exception... "Could not convert JavaScript argument"
nsresult: "0x80570009 (NS_ERROR_XPC_BAD_CONVERT_JS)" location: "JS
frame :: http://jqueryjs.googlecode.com/files/jquery-1.2.6.js ::
anonymous :: line 871" data: no]
Source File: http://jqueryjs.googlecode.com/files/jquery-1.2.6.js
Line: 871
I am relatively new to javascript and brand new to jQuery so this
informations doesn't help me much. Is this a bug? Or is my coding
simply bad? My html and css both validate at W3C.
If this is the wrong forum/list/group I apologize -- please direct me
to the proper place.
Thanks,
