Need help in flash based email with php

Ok…i know nothing about php but I followed the tutorial here in making email form-flash based using php. As instructed, i uploaded it to my server (yahoo) and after 100th time of testing…8-] trying to figure out whats the problem…i finally gave up and thats why im wriiting now asking for help.
I even made sure that the server plan i am with yahoo has PHP interpreter(i even upgraded it just for this).
So…what do you think is the problem? I downloaded the file from the tutorial and changed the “email address” to the address i want , then, i uploaded it to my server.

Sorry…after no sleep…dreaming on it…i feel like a zombie now…cheers;_D
