I’ve created two apps (for Coffe Bar), one is for the guest to order drinks and the other one is for staff to see new orders, they use the same spreadsheet. You can see it in action here https://youtu.be/BbL3lg79D_w
So when a customer orders their drinks and when waiter confirms he is finished with that order via CONFIRM BUTTON, i need to set the whole quantity column automatically to 0 (zero). The problem is that there is no way to do that, can someone help me with that?
