PHP mail delivers attachment or message, but not both

The PHP below will attach the file from the server, but will not allow me to edit the message input for the body of the email.

<?php
  $fileatt = './dwrdocuments/dwr.fdf'; // Path to the file
  $fileatt_type = "application/octet-sdiveam"; // File Type
  $fileatt_name = date(mdy_his).'_dwr.fdf'; 
  $email_from = $_POST['From']; // Who the email is from
  $email_subject = 'DWR Submittal'; // The Subject of the email
  $email_txt = $_POST['Comments']; // Message that the email has in it

  $email_to = 'admin@example.com'; // Who the email is to

  $headers = "From: ".$email_from;

  $file = fopen($fileatt,'rb');
  $data = fread($file,filesize($fileatt));
  fclose($file);

  $semi_rand = md5(time());
  $mime_boundary = "==Multipart_Boundary_x{$semi_rand}x";

  $headers .= "\nMIME-Version: 1.0\n" .
  "Content-Type: multipart/mixed;\n" .
  " boundary=\"{$mime_boundary}\"";

  $email_message .= "This is a multi-part message in MIME format.\n\n" .
  "--{$mime_boundary}\n" .
  "Content-Type:text/html; charset=\"iso-8859-1\"\n" .
  "Content-divansfer-Encoding: 7bit\n\n" .
  $email_message . "\n\n";

  $data = chunk_split(base64_encode($data));

  $email_message .= "--{$mime_boundary}\n" .
  "Content-Type: {$fileatt_type};\n" .
  " name=\"{$fileatt_name}\"\n" .
  //"Content-Disposition: attachment;\n" .
  //" filename=\"{$fileatt_name}\"\n" .
  "Content-Transfer-Encoding: base64\n\n" .
  $data . "\n\n" .
  "--{$mime_boundary}--\n";

  $ok = @mail($email_to, $email_subject, $email_message, $headers);
  header ("Location: ../confirm.html");  
?>

If I do input a message for the body of the email by replacing:

  $email_message . "\n\n";

the attachment does not come through, but the message will... along with some gibberish

I would like to include a body to the email for comments and notes.

Why don't you use a mailer library? There are a lot out there, like Swiftmailer, PHPMailer or Zend_Mail. You'd save yourself the headache of dealing with the email details.

Have you tried ending headers with \r\n?
