Automatic Tab Shifter

Automatic Tab Shifter

Hi everyone, I am trying to get the demo no jquery, where the Tabs automatically switch without changing URL's.
Here is the link to the demo I am trying to recreate. http://jqueryui.com/demos/tabs/

Here is the url to the page where I am trying to recreate the demo on http://www.mdplusclinic.com/test2.php

I included all of dependent jquery library, source code, and CSS files for the demo, and I still cant get it to work! arrrg!

Am I doing something small and stupid? that is preventing this easy demo from working?

Thanks Will-
