Custom Field in list.php file

[gofer123]

Hi folks,
I'm stuck! 
I need to have a custom field in the list.php file  I have placed the code below but I know it's correct but I've just been doing trial & error, the custom shopper field I created in VM is myrebate, this field needs to be a text field. Can someone please help, the client wants to launch this site and this problem is holding everything up.
Thanks in advance
<div class="rebate-field">My Rebate
<?php echo $this->currency->priceDisplay($row->order_myrebate, $row->order_myrebate); ?>  </div>
