I'm trying to get a simple accordion working but cannot seem to crack it, simple as the tutorial seems to be.

For some reason the accordion just doesn't display despite js being enabled on my browser (chrome 10).

Any clues as to what may be going wrong would be hugely appreciated as I've spent a couple of days trying to get this working.

Cheers,

Aaron
