Hi,
It been several months (and several release) that we are using tags for the emails.
It will be easier for you, specially when you want to display an address custom fields, knowing that you have one billing and one shipping address ; so you need to indicate from which one you want to display your field !

By the way, do not send me private message, use the "contact us" form instead.
