you just can not shut down the bracket! valid code is:

    <?php
if(isset($_POST['submit'])) {
    $to = "[e-mail]";
    $subject = "Contact Us";

// data the visitor provided
    $name_field = filter_var($_POST['name'], FILTER_SANITIZE_STRING);
    $email_field = filter_var($_POST['email'], FILTER_VALIDATE_EMAIL);
    $comment = filter_var($_POST['comment'], FILTER_SANITIZE_STRING);

//constructing the message
    $body = " From: $name_field

 E-Mail: $email_field

 Message:

    $comment";

// ...and away we go!
    mail($to, $subject, $body);
}
?>
