Well there she blows! Now I will attempt to add:
$myBcc = ( strpos($mail_message, '<!-- ORDER COMPLETE -->')===false ) ? '' : "Bcc:
YOUR_ID@trustpilotservice.com".$lend;
$headers = "From: ".$company_mail_from.$lend.$myBcc."X-Mailer: X-Cart".$lend."MIME-Version: 1.0".$lend.$message_header;
to the file. does it matter exactly where it goes?
