nested if vlookup excel formula

Question

=IF(DEAN=Hide_Only,IF(VLOOKUP(F5&$B$13,$Y$13:$AF$429,IF($Z$11=$B$6,2,IF($B$6=$AA$11,3,IF($B$6=$AB$11,4,IF($B$6=$AC$11,5,IF($B$6=$AD$11,6,IF($B$6=$AE$11,7,8)))))),FALSE)<D4,D4,VLOOKUP(F5&$B$13,$Y$13:$AF$429,IF($Z$11=$B$6,2,IF($B$6=$AA$11,3,IF($B$6=$AB$11,4,IF($B$6=$AC$11,5,IF($B$6=$AD$11,6,IF($B$6=$AE$11,7,8)))))),FALSE)),VLOOKUP(F5&$B$13,$Y$13:$AC$429,IF($Z$11=$B$6,2,IF($B$6=$AA$11,3,IF($B$6=$AB$11,4,IF($B$6=$AC$11,5,IF($B$6=$AD$11,6,IF($B$6=$AE$11,7,8)))))),FALSE))

So Far I have this excel formula, but it gives me #REFI error. This formula worked before I added AD,AE,AF columns into the formula. Is there any way to fix this error?

Answer 1

Check the definitions of the named ranges DEAN and Hide_Only. The #Ref error indicates a wrong reference and these are the only two references that are not spelled out in the formula.

A named range will return a #Ref error if the rows/columns it refers to are removed.
