Need help sending email with flash and php

i read the tutorial, [color=#003366]Flash[font=Verdana]-Based[/font][/color][size=2][font=Verdana][size=4][color=#003366][size=2] Email Form Using PHP, [color=#000000]and can’t seem to get it to work. i created the flash file and php files following the instructions and uploaded the files to the server, and tested it by trying to send an email to myself - didn’t work, so then i tried using the tutorial’s example files (changed only the email address to my own in the php file) and that didn’t work either. i’ve never used php before, so am i missing something else i have to do to the php file. could it also be a problem with a server? i tried it on another website server as well, and it also didn’t work there. i’m so confused - please help![/color][/size][/color][/size][/font][/size]

flash file attached and php code below:

<?php
$sendTo = “mmay321@yahoo.com”;
$subject = “New Mailing List Subcriber”;
$headers = "From: " . $_POST[“name”];
$headers .= “<” . $_POST[“email”] . ">
";
$headers .= "Reply-To: " . $_POST[“email”] . "
";
$headers .= "Return-Path: " . $_POST[“email”];
$message = $_POST[“message”];
mail($sendTo, $subject, $message, $headers);
?>
