Parse Error : Syntax Error

[fourteenStar]

Hi,

I am not able to get my email form working. Can anyone help me? I am using Expression Web 4. I am trying to make it work for a Linux Server. This is my email processor code:

<?php 

$to = '[e-mail]';
$subject = $_POST['phoneNumber'];
$header = $_POST['email'];
$message = "From: $fullname\nSender email address: $header\nRegarding: $subject\n\nMessage:\n$comments\n';

if ($header=="") {
   echo "<meta http-equiv=\"refresh\" content=\"0;URL=error.html\">";
   exit;
  }

$success = mail ($to, $subject, $message, "From: <$header>");

if ($success) {
 echo "<meta http-equiv=\"refresh\" content=\"0;URL=success.html\">";
 }
 else {
 echo "<meta http=equiv=\"refresh\" content\"0;URL=failure.html\">";
 }

 ?>

I keep getting the error:
Parse error: syntax error, unexpected T_CONSTANT_ENCAPSED_STRING in /home/content/n/j/x/njxc500/html/Pages/Contact/emailProcessor.php on line 9

Any help would be great!

Thanks
