Any chance you could wrap this in [code] tags and do some indenting? It would make it a lot easier to follow.

Thanks, but I don't think you've got the idea of indenting - it is supposed to reflect the hierarchical nature of the code and make it easier to follow.

I actually meant edit your original post, so there aren't several pages of code, not post it all again

Firstly, it's javascript, not java. They are totally different languages.

Have you tried my previous suggestion?

I've told you the alteration you should try.
I am not willing to offer any more help until I know the results of my first suggestion.
