Beginner PHP help, simple email form from flash not working

I am trying to make a simple email form in Flash. I have created the
form and saved it as a movie clip named Form. I embedded this clip in
my flash based website. I then added a submit button with the simple
script:

on (release) {
form.loadVariables("email.php", "POST");



}


I then put a stop action on a seperate layer and then insert one more
frame. On the movie clip "form" I added this script. The last frame I

added had a thank you for submission message.

onClipEvent (data) {
_root.nextFrame();



}


Now for my php file, I used this script in a file simply saved as
email.php:
<?php
$sendTo = "**My Email**@**My Domain**.com";
$subject = "Subject";
$headers = "From: " . $_POST["name"] ." "<" . $_POST["email"]
..">\r\n";
$headers .= "Reply-To: " . $_POST["email"] . "\r\n";
$headers .= "Return-path: " . $_POST["email"];
$message = $_POST["field1"] . $_post["field2"];
mail($sendTo, $subject, $message, $headers);

?>


When I upload the file to the server, the submit button does absolutely

nothing. Not sure what I did wrong.
