How do i setup Staff Discount on swipe card/nfc card and adding staff

I tried to do it as in the instructions, but it didn’t work. Is there an instruction for the 5th version? Please help to solve the problem. Make a tutorial for version 5. I have 10% for service and 20% -30% -35% discount cards, but discounts should not concern service. Ie (Amount - Discounts) + Service
Very grateful in advance.

Change the sort order, and kr check the plain/subtotal option or change to fixed and automate discount rather than generic fixed rate on total and used math and report expression to calculate.
We have 10% wet, 20% dry for regulars so that’s haw I did mine as wasn’t based on ticket total but specific orders/products.

Can you make any tutorial please ?
I’ll be very thankful

Pretty sure I discussed my setup in forum somewhere.
