Javascript Toggle crashing IE6

[terrybarnes]

I have a site that works perfectly in everything except IE6. My developer included a toggle button to show and hide a DIV but when I click the button it crashes the browser.

Any ideas would be much appreciated.

The page is here: <snip>

click on the "Tell a friend" link (this works okay in FF so you can see what is supposed to happen)

I think the .js file it's calling is here: <snip>

Any help would be very much appreciated - I'd like to get the site live today but also need it working in all browser and platforms before I do.

[edit reason] no URLs, please. Post code [/edit]

Forgot to mention that it's using the "Effect.toggle" command from Scriptaculous

Still not sure why that one won't work but I've found this one: [javascript.internet.com...] which appears to work correctly in all browsers.
