Why does my css menu displays correctly on FF and not on IE?

[londres9b]

I have this dropdown menu with some jquery effects.
This is not a normal "works on Firefox and not on IE" thing.

It works and looks exactly the same (the right way) on both FF and IE When the menu code is alone in one page.

But when I put it inside another page it stops working fine on IE!

Please help me I've been over and over the code and I can't understand why..

I've decided to leave this menu as it has too many browser compatibility issues.

You should validate your page and fix those errors. It looks like your path to fancydropdown.c ss is incorrect too.

I validated my HTML.. can't access CSS validator at the moment.

The problem persists, maybe it's the CSS.
