Need Drop Down Menu Help

Hello,

I'm in need of some styling help for my site at http://www.ufmcc.com. Specifically, the drop down menu on the far right. I need it to extend to upwards of four child links, but it extends to the right, off the screen and past the template border. I need to fix this asap and have no clue how.

Anybody game to help?

Thanks,
-Mel
