Two problems:
First, Your HTML is broken
Change
//BODY CONTENT 2// |
To
//BODY CONTENT 2// |
Second, HTML id's should be unique so I suggest using classes instead.
Here is a working example: http://jsfiddle.net/jkohnen/tBkh4/
I used .toggle() to simplify the jQuery a bit
Hope that helps, and Happy Coding.
