Hi,
I've been racking my brain trying to get this formula to work!
I can create a helper column in the sheet and display the number of children each row has, then simply use a CountIf function - if Children=0, but, I thought i could use a COUNTIF with @cell to not require the helper column?
I have tried the following
=COUNTIF({Ref Col}, COUNT(CHILDREN(@cell))=0)
Thank you
