My first theme getting dropdown menus to work in WP

Hey all,

This is my first theme and hopefully the first thing I contribute to WP.

My Dev work can be seen here http://duzawe.com/cb/
The Static pure html one can be found here duzawe.com/rd

I’m trying to get a drop down menu to work and I’m lost. Every time I go a googling I get crap results.

Can anyone help?

PS is there a more up to date version of the WP.css in this guide or something similar http://themeshaper.com/2009/07/07/reset-rebuild-wordpress-theme-css-define-layouts/
