Help with the flash mailer using php

i was working on this tutorial (http://www.kirupa.com/developer/actionscript/flash_php_email.htm)

it sends me a blank email. the only thing that it pulls from the form is the email field.

i have the vars filled out for the other fields.

the actions for the send buttons is this:

on (release) {
// send variables in form movieclip (the textfields)
// to email PHP page which will send the mail
form.loadVariables(“email.php”, “POST”);
}
on (release) {
gotoAndPlay(50);
}

the php file is the same as in the tutorial.

any help would be much appreciated.
