Making this script work to display multiple layers.

[americanqu33r]

I've set up a script on the site so that when you click the navigation at the top it displays the subnavigation. But I'm not good with JavaScript or DHTML for that matter and I'm not for sure how to go about setting the script to do it for each section "Info" "media" and "Other". Currently the media one works. If you could take a look at the site and script and help me out it would be much appreciaited.

Thanks in advance!
