I would like to be able to have the tracking number for each order associated with each record on the account history.
I have made a column in the order sheet of the database that is entitled "tracking_number" and I have edited the "tpl_account_histroy_info_default.php" and "accout_history_info.php" files and I have been able to create headers and tables and everything I need but i can't seem to figure out how zencart is reading in the values from the database based on the order number.

I have tried mimicking the php code using phrases such as

"<div><?php echo $order->info['tracking_number']; ?></div>"
or
"<?php echo $order->products[$i]['tracking_number']; ?>"

and they aren't doing anything. And I don't know enough about php to dare guessing anything else. If anyone can help me out that would be great.

My website is readyholster.com. I cant really send a link of the page in question as you have to be able to log in to see it.
Thanks for any help!
