Contact form , Får inte from: att funka

Hej håller på med en contact form allt funkar men den verkar inte vilja vilja visa från vem brevet är. Det står Uknown. Jag skickar med koden så får ni se.

// Build message.

function build_message($request_input){if(!isset($message_output)){$message_output ="";}if(!is_array($request_input)){$message_output = $request_input;}else{foreach($request_input as $key => $value){if(!empty($value)){if(!is_numeric($key)){$message_output .= str_replace("_"," ",ucfirst($key)).": ".build_message($value).PHP_EOL.PHP_EOL;}else{$message_output .= build_message($value).", ";}}}}return rtrim($message_output,", ");}

$message = build_message($_REQUEST);

$message = $message . PHP_EOL.PHP_EOL."-- ".PHP_EOL."";

$message = stripslashes($message);

$subject = "FixPix ". $_REQUEST['name'];

$headers = "From: " . $_REQUEST['email'];

mail($my_email,$subject,$message,$headers,);

?>
