Help !!!! Please!!!

There is something wrong with my sidebar,

http://www.stagenightlife.com/index.php?page_id=11

for some reason on some of the pages of my website, the side bar is all the way on the bottom of the page and not on the right side like it is supposed to be. I think its prob some easy fix, but im not an wordpress expert.

Can someone email me a solution? steve@stagenightlife.com
