multiple foreach loop?

Hi All, Trying to create a "refer a friend" script. User enters 10 names and email address of a friend to refer to a site. The following code SORT of works in that it will send the email, etc.. but problem is it duplicates - sends the email out twice to the same email address. **CODE*** foreach($nameRefered as $referedName) { foreach($emailRefered as $referedEmail) { if ($referedEmail != "" && $referedName != "") { <message body here> /* To send HTML mail, you can set the Content-type header. */ $headers = "Return-Path: <$support_email>\r\n"; $headers .= "MIME-Version: 1.0\r\n"; $headers .= "Content-type: text/html; charset=iso-8859-1\r\n"; $headers .= "From: $nameReferer <".$emailReferer.">\r\n"; mail ($referedEmail,"Your Order on Rinkrake.com", $message, $headers); } } } Any thoughts on why I get the email twice? Thanks all. Much appreciated! Aaron
