I have two columns.
primary and column B
On the parent row for column B, I want to look at any children which are ticked and then join collect distinct values from primary column.
If I was to do a basic formula in column B it would be this for children:
=JOIN(DISTINCT(COLLECT(CHILDREN(), CHILDREN(), <>"")), CHAR(10))
I want to return results from Primary column only where column B is checked.
any advice?
