need help with category sizing

[Fraze]

I'm just in the process of finishing my first ever vbulletin forum skin, but now that i've changed the forumbit_level1_nopost template, the widths on the visible sections have all gone haywire. I've attached a text file with my code in it. what can I do to make sure all the categories look the same?

here's the skin
