Calling all bloggers...

Help please, I have tried everything I can think of and I cannot figure out why our blog now has all of our stuff at the bottom instead of on the side. Anyone know what I need to do to fix this? It's really bugging me. I have tried changing the layout, the background, and even playing around with the HTML. I don't know what else to do...post a comment or email me if you have any suggestions. Thanks!
