Flash Forms using Radio Buttons /PHP- Help!

Please I need a little direction. I’ve created a form in Flash using input text and 3 groups of radio buttons ( 2 per group). I’ve written the PHP script to send the from via email.

This is what I recieve via email. How do I get the [object Object] to properly display the label name of the radio button?

Reunion Tickets: [object Object]
Mixer Tickets: [object Object]
Both Events Tickets: [object Object]

PHP Script:
<?php
$sendTo = “sharee@shareeneff.com”;
$subject = “Reunion Ticket Reservation”;
$headers = "From: " .$_POST[“name”];
$headers .= “<” .$_POST[“email”] . ">
";
$headers .= "Reply-To: " .$_POST[“email”] . "
";
$headers .= "Return-Path: " .$_POST[“email”];

$message = stripslashes($_POST[“message”]);
$message.="

Reunion Tickets: “.$_POST[‘ReunionGroup’];
$message.=”

Mixer Tickets: “.$_POST[‘MixerGroup’];
$message.=”

Both Events Tickets: ".$_POST[‘BothGroup’];

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