How can I show the custID on the orders.php page?

[DogLegs]

On the orders.php page I am needing to show more information when I get into the EDIT mode of an Order. I can easily show the Order Number by adding the code below.

                  <tr>
                   <td class="main"><?php echo "Order ID"; ?></td>
               <td class="main"><?php echo "$oID"; ?></td>
                 </tr>

 

BUT... I am having a heck of a time trying to show the Customer ID for the order. Any ideas?

 

Thanks,

Brian
