I am trying to create a template that will return the total balance of
transactions according to their aging. I receive reports showing invoice
number, balance due, due date in xls format, these are often several thousand
lines depending on the account. I want to create a template that will (with
minimal editing/preparation) show the balance due of transactions according
to past due age (over 90 days, 60-90, 30-60, 0-30).
