newbie mail() function

Hello! I am very new to php programming. I have been experimenting around with php's mail function and html forms. I have a generic HTML form with user_name, email_address, comments, and like_site as inputs on the HTML form. I have the following code in a seperate php file which the form calls: <?php $msg = "Sender's Full Name:\t$user_name\n"; $msg .= "Sender's Email Address:\t$email_address\n"; $msg .= "User Comments:\t$comments\n"; $msg .= "Did you like the site?\t$like_site\n\n"; $mailheaders = "From: My Web Site\n" 9>$mailheaders .= "Reply-To: $email_address\n\n"; mail("cangerer@ibsys.com", "Feedback Form", $msg, $mailheaders); echo ("Thank you $user_name\n<br>"); echo ("I appreciate your feedback\n\n"); ?> for some reason I get a parse error on line 9. If I remove the mailheaders variables the PHP script works just fine and emails the form to the correct address. Any help on this would be appreciated. It is probably something qyite simple. I just don't see it though. Thanks. Chad
