Hardcore javaScripter Help

I’ve been using this code for a while now, but all of a sudden it’s throwing javascript errrors on the line marked with a ** - I’m able to do much more menial javascript stuff, and this is ‘woosh’ straight over my head (I don’t even really understand the syntax in this function…

Is it something plainly obvious which is causing this to fall over?

You can see the page on the web:

where it’ll kick up a bucket of errors I’m trying to wade through…

Any help graciously accepted…

NEWSFLASH I’ve been given the go-ahead to completely do the Javascript again- anyone know where I can find info on scrolling div layers? I’m just about to google, just in case anyone’s pulling out their flamethrower…
:trout:

Thanks,
Andy
