make sure you are changing all three lines that use the recordset code:
$MailBody = $MailBody . $row_rsEmails['memberFirstName'];
$MailBody = $MailBody . $row_rsEmails['memberEmail'];
$MailBody = $MailBody . $row_rsEmails['memberPassword'];
anywhere that is using a recpordset reference in the email needs to have "$row_rsEmails" changed to "$RecipArray[$RecipIndex][0]"
