I am trying to set dates based on country - the US, CA, and UK are singular, whereas the EU, APAC, etc, have many countries (using OR).
=IFERROR(IF(OR(GEO@row = "US"), [Req. ETD Date]@row + 31, (IF(GEO@row = "CA"), [Req. ETD Date]@row + 55, (IF(GEO@row = "UK"), [Req. ETD Date]@row + 56, (IF(OR(GEO@row = "EU", GEO@row = "FR", GEO@row = "DE"), [Req. ETD Date]@row + 65, IF(OR(GEO@row = "CN", GEO@row = "TW", GEO@row = "ANZ", GEO@row = "PH", GEO@row = "SM", GEO@row = "JP", GEO@row = "TH", GEO@row = "KR"), [Req. ETD Date]@row + 14, [Req. ETD Date]@row + 30)))))), "")
