Post meta data is loading beneath sidebars

Hi, I can’t seem to figure out why the post meta data from my entries is loading beneath the sidebar; which leaves a very ugly whitespace between the content and the comments links when I make a shorter post.

I’ve searched over and over, and I believe that all of my div tags are okay. The sizes are good too. ( I think, I’ve played with them some )

I’m no expert, so I’d like any help I can get.

Thanks.
