You can see in this formula the Status (harvey ball) column defaults to Blue. It changes colors to Green, Yellow and Red with conditions from the Risk Rating Level column and it works perfect.
However, I want the harvey ball to turn Red if the Risk Rating Level is Extreme even if the Complete checkbox is checked.
=IF(Status@row = "Complete", "Blue", IF([Risk Rating Level]@row = "", "Green", IF([Risk Rating Level]@row = "Low (Okay to proceed)", "Green", IF([Risk Rating Level]@row = "Extreme (Put event on hold)", "Red", "Yellow")))))
