page height out of bounds

[swimmerbhs]

I was looking at are website and the height is wrong. At the end of the footer where it says ecommerce by cube cart. The scroll is not done it still looks like it has 2 more pages to go.

Any help can be appreciated.

In the file common.css, line 223, find the height property for #nav .navcontainer.
