Form sending to PHP to mail question

Okay i grabben the PHP from Sen’s tut on flash and php forms.
I added some more variables to fit what I needed but now the email won’t show up in my in box. And I want to be able to add a thanks.html page after they submit their information.

  * PHP 4.1.0+ version of email script. For more
  * information on the mail() function for PHP, see
 // First, set up some variables to serve you in
 // getting an email.  This includes the email this is
 // sent to (yours) and what the subject of this email
 // should be.  It's a good idea to choose your own
 // subject instead of allowing the user to.  This will
 // help prevent spam filters from snatching this email
 // out from under your nose when something unusual is put.
 $sendTo = "[email protected]";
 $subject = "Media Brand Partners | Contact Us";
 // variables are sent to this PHP page through
 // the POST method.  $_POST is a global associative array
 // of variables passed through this method.  From that, we
 // can get the values sent to this page from Flash and
 // assign them to appropriate variables which can be used
 // in the PHP mail() function.
 // header information not including sendTo and Subject
 // these all go in one variable.  First, include From:
 $headers = "From: " . $_POST["name"] . "<" . $_POST["email"] .">
 // next include a replyto
 $headers .= "Reply-To: " . $_POST["email"] . "
 // often email servers won't allow emails to be sent to
 // domains other than their own.  The return path here will
 // often lift that restriction so, for instance, you could send
 // email to a hotmail account. (hosting provider settings may vary)
 // technically bounced email is supposed to go to the return-path email
 $headers .= "Return-path: " . $_POST["email"];
 // now we can add the content of the message to a body variable
 $name = $_POST["name"];
 $company = $_POST["company"];
 $address1 = $_POST["address1"];
 $address2 = $_POST["address2"];
 $state = $_POST["state"];
 $phone = $_POST["phone"];
 $fax = $_POST["fax"];
 $email = $_POST["email"];
 $website = $_POST["website"];
 $product = $_POST["product"];
 $other = $_POST["other"];
 // once the variables have been defined, they can be included
 // in the mail function call which will send you an email
 mail($name, $company, $address1, $address2, $state);

This is the code. If anyone can help I would really appricate it.
