side bar will not align

Hi, I am trying to get my sidebar to move back up so it is level with the main content.

I have tried decreasing the width of the container tag, and so many other things I have forgotton. Can anyone point me in the right direction….maybe I just need to change my template as you can see there is nothing left on mine from the orginal template apart from this sidebar!!!
