PHP Contact Form, Reply To

[JamesU2005]

Can anyone adjust this so when the contact form is sent it puts the name and email address into the "From:". So when the user reads the email it will automatically have the Name/Email Address in the From section.

Thanks

<?php 
$name= $_REQUEST['name'];
$organisation= $_REQUEST['organisation'];
$phone= $_REQUEST['phone'];
$email = $_REQUEST['email'];
$radiobutton = $_REQUEST['radioQuestion'] ;
$mes = $_REQUEST['message'] ;


$arr= array();
	$arr[0] = "Name: ";
	$arr[1] = $name;
	$arr[2] = "\nOrg: ";
	$arr[3] = $organisation;
	$arr[4] = "\nPhone Number:  ";
	$arr[5] = $phone;
	$arr[6] = "\nEmail Address:  ";
	$arr[7] = $email;
	$arr[8] = "\nQuestion Selection:  ";
	$arr[9] = $radiobutton;
	$arr[10] = "\nMessage is:  ";
	$arr[11] = $mes;


$msg =  ($arr[0]. $arr[1] . $arr[2] . $arr[3] . $arr[4] . $arr[5] . $arr[6] . $arr[7] . $arr[8] . $arr[9] . $arr[10] . $arr[11] );
$headers="Contact Form";
ini_set("sendmail_from","MYEMAIL");
mail( "MYEMAIL", "Contact Form", "$msg", "$headers") ?>
