Thanks
Adding the following code block worked.
<?php
global $row_LostPW;
?>
When used with <?php echo $row_LostPW['elementName']?>
When I used this code block only the form value displayed in the email was with value username
<?php echo(isset($_POST['elementName'])?$_POST['elementName']:""); ?>
<?php echo(isset($_POST['username'])?$_POST['username']:""); ?>
Thanks
