Hi,
In table Courses, I have a "Related Lessons" field that is a link to table Lessons
"Related Lessons" field contains 3 Lessons' records: L1, L2, L3
In table Courses, I want to create a second field, named "Open Related Lessons" that contains 2 linked records only: L1, L2. The remaining L3 records should be excluded based on filters.
--> How to achieve that?
