I'm totally new to this, so bear with me. I'm setting up a navigation menu that has sublinks on hover. I decided not to specify different heights for each submenu, and used  (!$first.data('height')) instead. It seems to work fine in Chrome and FF, but not in IE. Can someone tell me how to fix it?

thanks in advance for any help on this
