Hi all,

I have set up an app for a restaurant that rewards customers with a free coffee after they purchase 10, I set a list up with a people picker and a column called coffee purchases, I then set the app up with a barcode scanner that updates the persons list by 1 each time they scan the barcode. I have then set a flow up that sends an email to the created by letting them know they have a free coffee when they have purchased their tenth, I want to now add into the flow to subtract 10 once the column is equal to or greater than 10, any help much appreciated.
