1) You have added that change to the webassist/email/templates/block_3.php file, but it needs to be added in the webassist/email/templates/templates.php instead
2) in the block 3 file, you are using this code:
[php]<?php echo($RecipArray[$RecipIndex][0]["[nome]"]); ?>[php]
to reference the recordset, it should be:
<?php echo($RecipArray[$RecipIndex][0]["nome]"); ?>
