I'm designing a site using a CSS layout (center area, left menu, and top banner area), and for one page, I want two columns of info. Since I'm doing all the widths in percentages, I can't get a table to work in the divs, so I thought I'd just make a separate page with the columns of info and insert it as a SSI on the page I wanted. I left that page free of all CSS formatting so it wouldn't interfere with the CSS I'd applied to all the pages. I thought this would all work hunky-dory, but it doesn't, and I don't know what's wrong. If someone could take a look at my files and see if they can pinpoint the problem, I'd be so grateful!

http://www.valeriejune.net/problem01.shtml - this is how the main page looks with the SSI page as it is.

http://www.valeriejune.net/problem02.shtml - this is the page I'm including, and how the spacing ought to be.

http://www.valeriejune.net/problem03.css - this is the CSS layout applied to the main page.

http://www.valeriejune.net/problem04.shtml - this is how a regular page with the CSS layout looks.

I know I sound like I want someone to do all this work for me, but I've been agonizing over this for hours and I don't know which way to turn.
