Model number list in cart?

I may have turned this off a couple of months ago can't remember... For when a customer clicks "My Cart" and it shows the product, the attribute selected.... How can I get it that the model number is listed in with that

I have found this forum, but doesn't work. I am using zen-cart 1.3.8a I would like the model numbers to show as listed in that post... in the shopping cart, order confirmatione etc.

sorry for the triple post for got to show the link to the above post http://www.zen-cart.com/forum/showthread.php?t=64280&highlight=model+number+in+shopping+cart

in your tpl_shopping_cart.php

put this code under the following code around line 86.. that says
<a href="<?php echo $product['linkproductsname .........

<?php echo '<br />Model:' .zen_products_lookup($product['id'], 'products_model');?>

just copy and paste this code.

do the same thing for other files that were mentioned in other forum. no need to replace anything.
