Good morning Knackers!
I am in the process of building an app for an equestrian center to track student progress. I’ve gotten most of the functionality I want to be created in Knack except for one. Currently, students buy credits which are then deducted for every lesson they take with a teacher. Typically a student would buy 4 credits a month and then take 1 weekly lesson. Each lesson would then subtract a credit.
What approach would I take to be able to give credits to a student and then for every completed lesson it would deduct from their credit balance?
