Editing the Vertigo theme

Hello Everybody,

I’m using the Vertigo theme. The problem is, the navigation bar is quite low in the theme. Down in the footer. Beneath my posts.

After much struggling I’ve at long last managed to hoist it up, so it now sits under my my logo. (where I want it).

However, when I post anything, video, images, blog, etc. they push the navigation bar back down the page again. How do I post beneath the navigation bar?

Thanks
