Simple CSS Nav Issue

[copilotDesign]

I'm having trouble getting the http://netwaiter.com/newsite nav bar to rollover correctly. In particular, the drop-down list rollovers in the "Products & Services" tab, I'm trying to get to fully highlight instead of the padding on the left.

Can someone glance at the CSS and tell me what the heck I'm missing?

Thanks!

This should get rid of the extra space
#nav li ul li {
float:none;
padding:0;
margin:0;
}
