How do I get rid of this space?

I give up, almost, I can't figure out why there is a space between my top level links and my sub-links just below.

How do I get rid of this space and have the dark blues butt up against each other?

Attachments have to wait to be approved. Better to post a link or your code.

Didn't have anywhere to post it publicly. Getting rid of this space is driving me crazy.
