Site is http://halcyon-hotsprings.com

I have a small script that is designed to resize my inline frame. Currently it works in ie, safari and chrome, but does not work in firefox or opera.

This is a huge headache that I have been trying to solve for more than a month and am really stuck.

The worst thing about it is that not only does it not work in firefox or opera, it makes the frame completely invisible. So the site is essentially completely broken in these two browsers.

If anyone could help with this I would be so grateful - or even if you have a better suggestion as to how I could have the site look the same but without inline frames?
