email file attachment does not send

[voll]

I have a form thats sends information and a file attachment. I have the code written and everything seems to be correct, but when I submit the form, all I recieve in my email is the data and no file attachment. Here is the code:

<?
 // Obtain file upload vars
$fileatt      = $_FILES['fileatt']['tmp_name'];
$fileatt_type = $_FILES['fileatt']['type'];
$fileatt_name = $_FILES['fileatt']['name'];

 $toaddress = "[e-mail]";
 $subject = "Submit Resume Form Response";
 $headers .= "From: Company Name<[e-mail]>\r\n";
 $headers .= "X-Sender: <[e-mail]>\r\n";
 $headers .= "X-Mailer: PHP\r\n";
 $headers .= "X-Priority: 3\r\n"; 
 $headers .= "Return-Path: <[e-mail]>\r\n";

if (is_uploaded_file($fileatt)) {
 // Read the file to be attached ('rb' = read binary)
  $file = fopen($fileatt,'rb');
  $data = fread($file,filesize($fileatt));
  fclose($file);

 // Generate a boundary string
  $semi_rand = md5(time());
  $mime_boundary = "==Multipart_Boundary_x{$semi_rand}x";

 // Add the headers for a file attachment
  $headers .= "\nMIME-Version: 1.0\n" .
              "Content-Type: multipart/mixed;\n" .
              " boundary=\"{$mime_boundary}\"";
  // Add a multipart boundary above the plain message
  $mailcontent = "This is a multi-part message in MIME format.\n\n" .
             "--{$mime_boundary}\n" .
             "Content-Type: text/plain; charset=\"iso-8859-1\"\n" .
             "Content-Transfer-Encoding: 7bit\n\n" .
             $mailcontent . "\n\n";
  // Base64 encode the file data
  $data = chunk_split(base64_encode($data));
 // Add file attachment to the message
  $mailcontent .= "--{$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";
}

 $mailcontent .= "First Name:\n".$first."\n\n"
 						  ."MI:\n".$mi."\n\n"
						  ."Last Name:\n".$last."\n\n"
 						  ."Address:\n".$address."\n\n"
						  ."City:\n".$city."\n\n"
						  ."State:\n".$state."\n\n"
						  ."Zip:\n".$zip."\n\n"
						  ."Email:\n".$email."\n\n"
						  ."Phone:\n".$phone."\n\n"
						  ."Work Phone:\n".$wphone."\n\n"
						  ."Cell Phone:\n".$cphone."\n\n"
						  ."Term:\n".$term."\n\n"
						  ."Salary:\n".$salary."\n\n"
						  ."Availability:\n".$availability."\n\n"
						  ."Desired Position:\n".$desired_position."\n\n"
						  ."Objective:\n".$objective."\n\n"
						  ."Experience:\n".$experience."\n\n"
						  ."Interests:\n";
for($i=0; $i < count($interest); $i++) 
{
$mailcontent .= "".$interest[$i]."\n";
}
     $mailcontent .= "\nEducation:       ".$education."\n\n"
							  ."License:           ".$license."\n\n"
							  ."Skills:               ".$skills."\n";
	   		// Send the message
			mail($toaddress, $subject, $mailcontent, $headers);
?>

Any ideas on why I don't get the attachment?
Thanks in advance for any help I can get, I'm stumped.
