I am trying to use the below formula to collect LOB based on the Functional unit and Managing office provided. I am referencing another sheet which contains a matrix of Functional Units and Managing offices that fall under certain LOB
=IFERROR(INDEX(COLLECT({LOB}, {FU}, CONTAINS([Functional Unit (Dept ID)]@row, @cell, [Managing Office (Estab ID)]@row, @cell)),1)"No Result")
