Why doesn't this menu work?

I'm building a cascading menu using CSS. I've done it before, but I'm still pretty new to this, hence my current quadary.

Head out to http://muscularchristianityonline.com/campus/about.php I'm trying to get the "About" link on the nav bar to open up a pull down menu just like I did when you head out to http://www.countryshowdown.com. But I'm missing something and I don't know what.

How do I get my pulldown menu to show up? I should be able to hover over "About" and see another menu option, but it's not working and I don't know why.

It's opening for me in Firefox.  You just need to adjust the top value from 100px to 45px in the #nav ul

I see what you're talking about, but it doesn't change anything in IE. Is there anything else that's lacking?

Thing is, the exact same infrastructure is at countryshowdown.com. This should work and I don't know why it doesn't.
Your missing a doctype.  It's throwing IE into Quirks mode.  You can use the HTML 5 Doctype or you can use another one. But you NEED a doctype.

I went with <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">, but while it works in Safari, it doesn't work in IE.

What can I do to make it cross platform friendly?
Actually the Doctype is something like this:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"

Or if you want to use the new HTML5 stuff:
