Class not being applied and other issues

Class not being applied and other issues

To start, I would have searched had I known where to start but since I don't here I am.

Simply, I am having issues with part of my JQ code not running. I am working from examples and marking up my HTML and CSS properly (as far as I can tell).

Take a look at http://zasper.com/funky/index.html and notice the menu section works (using JQuery) yet all the h3 tags are still showing and the requested addition of a class to the first H3 is not being applied. When added manually the header sits in the correct location so I know its not the HTML or CSS. I understand my JQ code does not address the p tags, I was testing on the H3 tags alone.

Any suggestions on whats wrong. The examples I am following are working and my page is working, just not w/ some of the JQ code.
