Adding a JQuery menu problems

I have simplified a design just to get it working but i still cannot add
the menu is working as hand code
http://bg01.waynedge.com/demo/index_empty.html
but i get an uncaught TypeError (undefined is not a function). I have placed the code just about everywhere
what gives?
frustration mounts, somebody please help. This problem can be fixed outside easily of webflow but defeats the purpose of having webflow.
