I enabled Payment Links with Freedompay a few days ago. I have been trying to add "Amount Paid" and "Amount Remaining" fields to my advanced PDF invoice, but cannot find the fields in the records list. I have attempted to add these using the ${record.amountpaid} and ${record.amountremaining} fields after my ${record.total} row, but either nothing is populating or I get an error.

What I want to achieve is to show Invoice total, Amount Paid and Amount Remaining in three rows, in that order. We had this functionality with our previous credit card processing profile (Versapay), but it no longer works.
