SELECT (SELECT COUNT(*) + 1
FROM History H INNER JOIN
Lifter L ON L.uidLifter = H.uidLifterRef
WHERE L.uidClassRef = Lifter.uidClassRef AND
H.ScoreTotal > History.ScoreTotal) AS Rank,
Lifter.LifterNumber AS LifterNumber,
Lifter.Lastname AS Lastname, Lifter.Firstname AS Firstname,
Class.Description AS CDescription,
Activity.Description AS GDescription,
History.ScoreTotal AS ScoreTotal
FROM Class, Lifter, Team, History, Meet, Activity
WHERE (Meet.MeetDate = DATE ()) AND Team.TeamStatus = 0 AND
History.ScoreTotal > 0 AND
Class.uidClass = Lifter.uidClassRef AND
Lifter.uidTeamRef = Team.uidTeam AND
Lifter.uidLifter = History.uidLifterRef AND
Team.uidMeetRef = Meet.uidMeet AND
Lifter.Gender = Activity.Code
GROUP BY uidClassRef, Lifter.LifterNumber, Lifter.Lastname,
Lifter.Firstname, Class.Description, History.WeightScoreC,
Lifter.Gender, Activity.Description, Activity.Activity,
Lifter.LifterStatus, History.ScoreTotal
HAVING (Activity.Activity = 'GenderStatus') AND
(Lifter.LifterStatus = 0)
ORDER BY VAL(Class.Description) ASC, Lifter.Gender DESC,
History.ScoreTotal DESC

I would like to see the query only returns the top three of each group to help me determine the GOLD,SILVER and BRONCE position in each division. I know that I need a select in the WHERE part but how?
