page works in IE, doesn't in mozilla. :(

just wondering if anyone has any ideas. i haven't tried this setup before, so it's not working. i have an i-framed paged, in the middle of a 3-row table. the top and bottom item are static size and such, but i want the middle to be relative height. it seems mozilla reads a relative height for i-frames, but it won't read it for tables (why it does this, but _does_ render static height i don't know). anyways, the only way i've seen to make a table a relative height (100%) is to use a rather elaborate frame set, which i don't want to do. it's annoying, and there has to be aother way around it. the page looks exactly how i want it to in IE, but it has some shortcomings in mozilla
