shipping.tplinvoice.note-tab.tpl
In the shipping.tpl file, customers can enter a delivery message (line 84-85: <label for="delivery_message">)
This information appears in the new order email that is sent to me (file: new_order.html, lines 104-122).
What do I need to do to display the delivery message on the invoice?
I've tried several possible variables: $order_invoice->note, $note, $delivery_note, $message
