Why will one of my Divisions not show up?

I need some help figuring out why my division with an id of left will not show up on my screen. Thanks!

Here is my HTML:


and here is my CSS:


and here is one last image that is what i get from these two pieces of code

Thanks so much for the help! This one is really puzzling me!

Thanks so much! Such a small mistake can make such a big difference!


Please refrain from using so many pictures in the future. Try and keep it to a minimum.

Thanks, JibblyJ.
