Navbar dropdown not displaying properly

Hi,

I’ve been trying to fix how the navbar displays, specifically the dropdown menus. I’ve been playing around with the CSS and still I couldn’t fix it.

I don’t know if I’m allowed to post the link to the site I’m doing (mods, just remove it if it’s not allowed and let me know) but you can see how messed up it is here: http://totalenhance.com/site and I based the navbar from here: http://4x4ph.com/site

Please help. Thank you.
