Then this query with your table and field names --
SELECT DISTINCT CarlosDante.Account, (SELECT COUNT([XX].ClientID) FROM CarlosDante AS [XX] WHERE [XX].Account = CarlosDante.Account AND [XX].Amount BETWEEN START AND END) AS ClientCount, (SELECT SUM([XX].Amount) FROM CarlosDante AS [XX] WHERE [XX].Account
= CarlosDante.Account AND [XX].Amount BETWEEN START AND END) AS SumOfAmount, GroupTens.Group
FROM CarlosDante, GroupTens
WHERE ((((SELECT COUNT([XX].ClientID) FROM CarlosDante AS [XX] WHERE [XX].Account = CarlosDante.Account AND [XX].Amount BETWEEN START AND END))>0))
ORDER BY CarlosDante.Account, GroupTens.Group;
