Rather than continue on a thread that has no relevance to what I wanted ive started a new one.
Ive searched and haven’t been able to come across the solution, I noticed that @JTRTech did give the same scenario, however the solution wasn’t said (unless I missed it?)
Customer orders drinks, customer then gives loyalty card for alternate price list, card is swiped… prices aren’t updated. New drinks added to order have new discount.
Ive tried the Update Order action, Update Ticket action, but still cant work it out?
Yeah, and its all set up within my POS… however, If I create a button called Update Prices and press it… it updates ALL of the prices, which is what I want.
If I set the AMC to execute within a rule, it doesn’t. I thought maybe its because I have the actions in the wrong order, but they aren’t. Ill post screenshots of the layout:
It wont be exactly the same as the command triggering that uses a script to filter out swipes if its the current users own discount card and some other bits but the command value is the price list but you can change it to use entity data or whatever.
ill try it, but there is still no return from the data box anyway…
If I remove the constraints, the whole thing works sweet… apart from it uses every single SquareCard Customer Card… whereas I only want it to be ones with VIP Level 1.
I used Select Orders action
