Order Status Page: how to access fulfillment information on Additional Scripts ?

[chefJuanPi]

Hi 

I need to add extra information depending the carrier and tracking url used to fulfill the order.  To accomplish that I try to use Additional Scripts area of Order Status Page.

I try to Access the liquid object {{ fulfillment }} without success

{{ fulfillment }} show empty

{{ fulfillment.tracking_numbers.size }}  shows empty

{{ fulfillment.tracking_url }} give me an liquid error tracking_url doesn't exist

I can't find it on checkout.order either.

any ideas?
