I have an example here that subtotals bill amounts: https://pines.georgialibraries.org/dokuwiki/doku.php?id=circ:workstations:receipts#subtotals
I haven't tested this scenario, but you should be able to do something similar... 1) Set up am empty variable before the ng-repeat loop: <div ng-init="transactions.subtotal = 0"> 2) Somewhere inside the loop do some math: <li ng-init="transactions.subtotal = transactions.subtotal -- checkout.copy.price"> 3) After the end of the ng-repeat display your subtotal: <div>You Saved: {{transactions.subtotal | currency}}</div> Terran McCanna PINES Program Manager Georgia Public Library Service 1800 Century Place, Suite 150 Atlanta, GA 30345 404-235-7138 tmcca...@georgialibraries.org On Tue, Feb 13, 2018 at 3:29 PM, John Amundson <jamund...@cwmars.org> wrote: > Hi, > > We are preparing for our move to the web client and are currently going > through and updating print templates.
