Blog help!

I need help with this dumb blog! I have no idea what I did but all of my stuff that was on the side is now on the bottom of the page. I took my background off because I thought that was what was causing it, but that didn't work. I have tried every template that blogger has and it still isn't right. I can't figure it out and I don't like it being at the bottom of the page. If any of you computer savy people know what I can do please let me know. Thank You!!
