Additional date rollup fields

Avi Janssen

I need to create 6 additional date fields that function like Start Date and End Date. Namely, the parent should be a rollup of the children. If I set =MAX(CHILDREN()) as a column formula, I can't enter any data into the child rows. Is there a better way than having separate fields for parent and children?

Just enter this as a cell formula in parent row, NOT as a column formula.
