Thanks for the help.
Here’s what I finally done. Still testing but seems to work well.
[code]
<?php echo $this->__('RMA') ?> <?php echo $this->__('RMA #') ?> <?php echo $this->__('Order #') ?> <?php echo $this->__('Date') ?> <?php echo $this->__('Status') ?> <?php echo $this->__('Return Type') ?> [/code]
