Beveled Box Problem

[cgmcconnell]

I'm having an issue where, when I bevel the edges on my box model and hit the 3 key to preview the smoothed mesh, it doesn't seem to hold the outside edges. Am I missing something obvious here?

Hi!

It seems some of your faces are not connected or you have faces on top of each other.
