footer isn’t sticking in wordpress theme

I know this has been posted several times, but I might have made a mess of my code here, and need some help in tangling it out.

I want to make a sticky footer inside the wordpress theme i have styled.
For the sticky footer i have been using this tutorial:

I was hoping someone could firebug it and tell me what the issue is.

Here is a link to the website I’m building with problems and all:
