Sending data to PHP via AS3 Problem

In order to do something later down the road, I was using a more basic example from a tutorial about sending something to php script on a server using a URLloader. However it does not work. It tries to send, but the Event.COMPLETE event never fires.

Any ideas?

I’ve attached a zip containing the relevant files, and here they are on a server:

Thanks to anyone who can point me in the right direction.
