Health and Status roll up from task to child to parent

Gabby Nepomuceno

My roll-up formula in my parent row is working perfectly and captures the information from its primary children rows.

=IF(COUNTIFS(CHILDREN(), "Red") > 0, "Red", IF(COUNTIFS(CHILDREN(), "Yellow") > 0, "Yellow", IF(COUNTIFS(CHILDREN(), "Green") = COUNT(CHILDREN()), "Green", IF(COUNTIFS(CHILDREN(), "Blue") = COUNT(CHILDREN()), "Blue", "Green"))))

As others have asked, it doesn't pick up changes in secondary children rows and ideally, I don't want to manually copy/paste the parent formula to each primary child. Is there a way to have a parent row reflect changes to secondary, or even tertiary, children?

Replace the CHILDREN function with the DESCENDANTS function.

Awesome, the parent row now picks up all the descendent information. It looks like I still have to paste the formula (with the change to descendants) into each primary child for it to roll-up the information. Is there a way to make it a column formula? Something like, if there are descendants, then use the formula; if there are no descendant, then don't do anything (i.e., leave it blank)?
