Extending left column

Here's is a preview of the site:

What I needed was that the content box and blue bar on the left stretched when more content was added. This means I can't use a fixed height. The height was originally 900px for the content, and 880px for the blue bar. This should be the minimum, so I set the min-height for both divs.

The content box stretched perfectly, but the blue side panel doesn't seem to want to go past its min-height. I want it to go all the way to the bottom (the bottom margin and stuff can be changed after).

I set #bluenav to height: 100%, hoping it would go all the way down, but that doesn't work.

I'm not sure what to do. Can anyone help?
