Passing variable from PHP to textfield into movieclip

Hello

I’ve a contact formular from www.peopleforfun.com and I try to put the whole stuff into a movieclip. All is working perfect except the response from my php script to the textfield into a movieclip. It’ working only if the textfield is on the mainstage (_root).
My sample file:
http://www.younggods.com/xxy/test.fla

My php script:

<?php
$TextVariable = '&risultati=';
$response = 'Message gone... Thx!';
echo $TextVariable;
echo $response;
$recipient = "nome@mysite.com";

$subject = "[The Young Gods]  XXY Flash contact";
$date = date( "d/m/Y - H:i:s");

$msg = "You got mail! Your message :
";
$msg .= "-------------------------------------

";
$msg .= "Name:   $nome
";
$msg .= "EMail: $email
";
$msg .= "WebSite: $url

";
$msg .= "Message: $commenti

";
$msg .= "-------------------------------------
";
$msg .= "sent: $date";


// Send to TYG
mail($recipient, $subject, $msg, "From: ".$FirstName." <".$email.">");

// Send cc to sender
mail($email, "[The Young Gods] Thank You","Automatic Responder

Any idea?
I wish to include the response on the textfield “risultati”.

Thx for your help and time.
