PHP - Flash email form, add variable to message

Hello all,
I’m sure this will be easy for someone, but I’ve exhausted what little PHP knowledge I have. Here’s the deal: I’m using flash to upload a file and email me some info that the user entered in some forms on the flash side. All I want to do is add a url to the image that they uploaded into the body of the email. Here is my code:

<?php
if ($_FILES['Filedata']['name']) {
	$ran = rand();
	$ran2 = $ran."_";
   $uploadDir = "user_img/" . $ran2;
   $uploadFile = $uploadDir . basename($_FILES['Filedata']['name']);
   move_uploaded_file($_FILES['Filedata']['tmp_name'],$uploadFile);
	echo " ";
}
// email
$sendTo  = "myEmail@email.com";
$subject = "Subject";

$headers = "From: " . $_POST["name"];
$headers .= "<" . $_POST["email"] . ">
";
$headers .= "Reply-To: " . $_POST["email"] . "
";
$headers .= "Return-Path: " . $_POST["email"] . "
";

$message = $_POST["message"];

$body = $message . $uploadFile;

mail($sendTo, $subject, $body, $headers);
?>

I’ve tried a bunch of different things, (this is the latest one I tried) and still no luck. It sends the uploaded url, but no message and also no from “name” or “email” is displayed.

any help would be great. Thanks.
