Dynamic Headers pushed entire website down

I was really happy to find this plugin… I don’t really know php (I’ve got a little CSS), but I got it installed and working pretty well.

I was wondering if anyone had any high level ideas on what might be going on – here is the website: http://barn.motivespace.org/

It seems like it’s putting the header in the straight top of the website, and pushing everything down. Did I put the php line of code in the wrong place on the header file, do you think?

Any ideas would be greatly appreciated!
