Formating help

[sokol]

VB: 3.5.4
VBA: 2.1.0

Issues:
Ok, as you can see from here: http://vanguardlibrary.com/screenshots/vb-ss1.gif

The color of the "Page Background" is over flowing the actual Main Table Width of 900px.

If I change the Main Table Width in the Control panel, from "900px" to just "900"
it looks great like so: http://vanguardlibrary.com/screenshots/vb-ss2.gif

However doing this messes with the format of some of my other pages like so: http://vanguardlibrary.com/screenshots/vb-ss3.gif

Any one know how I can have the tables not over run the right side, but yet retain the background color I want?

Thanks,
Sokol
