Trouble adding Product description in the admin orders page

I have read most of the threads on how to add the description to the order in the admin area and none seem to work.

I am using zen cart 1.3.8

I need to add the description directly below the
title so I thought if changed line 475 in admin/orders.php to

<td class="dataTableContent" valign="top">' . $order->products[$i]['name'].'<br />'. $order->products[$i]['description'];

It would work but this does not appear to work.

Its ok I needed to change the query in admin/include/class/order.php

and change the corresponding arry

The lines I change
are 115.
I added products_description to the query

then I edited the array at line 145
and added

'description' => $orders_products->fields['products_description'],

below

'model' => $orders_products->fields['products_model'],
