in the pages you sent the to address is not using a recordset loop, it is using one email address from the rsMemClub recordset.
also the recordset you are trying to reference in the email body is a different recordset.
the code i have been giving you is for a recordset loop.
since your not using a recordset loop,
add this code at line 2 of the /waue_sendmessage_1.php:
and go back to the recordset referance for the email body:
$MailBody = $MailBody . $row_rsEmailRecipients['FirstName'];
