I have an app where users can sign up on a course program that takes for example 20 days.
Inside a course data I have data type for list of days (20 days on a list, orderfrom 1-20.)
I have a data type for a Start Day data type too and when user signs up on a course I save on a “my courses start day” list with the curse info under user profile.
I just try to figure out how to calculate and show course day on a calendar or on a current day if course days number = current day - equals users start day on that course?
Let’s say users course start day is 1.12.2018
I want to conditionally filter out days that are current day -minus- start day. For some reason I seem to struggle to do it.
