Here is what I attempted (after tying to find help in the community threads):
=AVG(COLLECT([# of Hours to Complete]:[# of Hours to Complete], [Conciere?]:[Conciere?], ="Y"))
This returns a #Divide by Zero" error
Here is what my sheet looks like, and I need to AVG. the # of hours for all rows that have "Y" in "Conciere?" column
Sounds simple enough but I just can't troubleshoot this one - Thanks in advance for any help you can give me with this formula
