So I used the formula below to count the courses in my helper field Course Count. I don't want to see the "zeros" in fields that are empty. So, how do I fix that?
=COUNTIF(Courses@row, HAS(@cell, "Wound")) + COUNTIF(Courses@row, HAS(@cell, "ostomy")) + COUNTIF(Courses@row, HAS(@cell, "continence"))
