I have a service request sheet with an index/match formula to assign a person based on request type. My formula works for all request types except "External Communications" - it assigns the wrong person. I tried creating a new "Assigned To Lookup" reference sheet, manually entering all fields, and yet the error persists.
=INDEX({Assigned To Lookup Range 1}, MATCH([Request Type]@row, {Assigned To Lookup Range 2}))
