Hi everyone

I'm trying to modify a PHP mail form script (called contactme.php) to redirect to a thank you page when the submit button is clicked.

The form script is below in its entirety - the line I'm using is:

           header('Location: http://awebsite.com/thankyou.htm');
           exit();

- but I'm getting this error message:

Warning: Cannot modify header information - headers already sent by (output started at /home/sites/awebsite.com/public_html/contactme.php:6) in /home/sites/awebsite.com/public_html/contactme.php on line 40

Is this something in the script, or something set by the system admin of my web host?

Any advice or solutions welcome

Thanks in advance,
Paula

contactme.php:

<?php

       if ($_REQUEST['step'] == 1)
       {
           $name = $_REQUEST['name'];
           $email = $_REQUEST['email'];
                 $comments = $_REQUEST['comments'];
                 $sendto = "me@here.com";

           // Compose simple text message:
           $message = "Message from $name \n\n\n$comments";

           // Send message to me
           mail($sendto,"Message from website",
                        $message,
                        "From: $email\n".
                        "Reply-to: $email"
                        );

           // Thank the generous user
           header('Location: http://awebsite.com/thankyou.htm');
           exit();
       }
       else
       {

       ?>
