1. A subselect must have only one row with one field.
2. If you want to connect a subselsect with the outer select, you have
to write a correlative select.

SELECT "event_name", "first_name", "middle_initial", "last_name",
"sex", "age", "email", "place",
CASE
    WHEN "age" BETWEEN 0 AND 18  THEN 'Youth'
    WHEN "age" BETWEEN 19 AND 59 THEN 'Adult'
    ELSE 'Senior'
END "Group",
CASE
   WHEN "place" <= 3 THEN ( SELECT "finish" FROM "Ribbons"
      WHERE "ID" = "a"."place" )
   WHEN "place" >= 4 THEN ( SELECT "finish" FROM "Ribbons"
   WHERE "ID" = "4" )
END "Finish",
CASE
   WHEN "place" <= 3 THEN ( SELECT "ribbon" FROM "Ribbons"
      WHERE "ID" = "a"."place" )
   WHEN "place" >= 4 THEN ( SELECT "ribbon" FROM "Ribbons"
      WHERE "ID" = "4" )
END "Ribbon"
FROM "Results" AS "a"

With "a"."place" the subselscts reads the value of "place" from the
current row, which is read out from "Results".

Regards

Robert
