I know I'm close.
If (DomainName($feature,"REVIEW_STATUS") = 1 or 3) then {return DomainName($feature,"TASS_REVIEW_STATUS")} = "Other")
I"m trying to have it label where If the Review Status is 1 or 3 then TASS Review Status = Other
1 and 3 are domains of review status and Other is a domain in the TASS Review Status field
