If this is your aliasing of the table, it doesn't look right.
[AgedAR] AS I2 ? As for the other field you want, just add it to the first select portion?
Using my own table/field names last night, I had this, which seems to work
Code:
SELECT tblTop5.payor, tblTop5.aging, tblTop5.amt
FROM tblTop5
GROUP BY tblTop5.ID, tblTop5.payor, tblTop5.aging, tblTop5.amt
HAVING (((tblTop5.amt) In (SELECT TOP 5 AMT FROM tblTop5 AS T WHERE T.[payor] = tblTop5.[payor] AND T.aging = tbltop5.[aging] ORDER BY AMT DESC)));
