well the page you linked to had no style,, well you know what i mean,,
i use Firefox as you may be able to tell by the shot, with the
Web Developer extension it lets you outline boxes and the CSS is on the right see the little button says CSS it has view, edit , disable, etc. the edit lets you do it live so you can watch your page change rite b4 your i's

and the
IE Tab ext. it lets you view it as IE inside of Firefox in another tab, and of course right click view source,,
so what i did to get that pic. was to go to the page that looks ok and copied the CSS in the rite hand side then went back to the first page and pasted it in the CSS window and,,, look at that p00f!
that leads me to think some how your CSS is not attached to that page or template. do the two pages have a diff. template? go to Layout>Templates on the right side you will see a little button that says css clik that and you can see what's attached,, course you've already have done that otherwise it would not have it in the CSS window from the W.D. bar,, so the only other thing mite be there are a lot of commented things in the CSS, all it takes is 1 wrong /* at the beginning and the whole thing will be ignored.
