css menu/site map problem

Using a tutorial for a css menu I've managed to achieve the drop down menu I
was after but would like to add a sitemap page in case browser or
accessability issues prevent it being displayed or used correctly. I copied
the unordered list and removed the 'id="nav" but it's still not viewing as
an unformatted list. How can I edit my CSS to seperate the two menus?
