chained select works on local host but not server

[mrsnappypants]

the subject pretty much says it, and I can't seem to figure out why, i've tried changing post to get, and the files paths are correct, even tried the file paths with the whole url. I have a unix server.
Any idea why this might be happening? I was up all night trying to figure it out.

no there's no js errors

here's a link to the script which works fine on my localhost
