Queries :: MAX Date Of Records - Add Another Field But Don't Want It To Group On It

I have a query that feeds another query. The first query needs to carry the Primary key, a secondary key (grouped by) a date (Maxed on) and an operator key (to group on) ...

At the moment I cant include the primary key because it groups on it and therefore every transaction is reports, my sql is -- How can I include the primary key MatterContactsMadeId and still get the max date for an operator within a matter

Code:

SELECT MatterContactsMade.MatterId, Max(MatterContactsMade.DueDate) AS MaxDueDate, MatterContactsMade.Operator
FROM MatterContactsMade
GROUP BY MatterContactsMade.MatterId, MatterContactsMade.Operator
HAVING (((Max(MatterContactsMade.DueDate))<=[Forms]![MattersBUpLogOptionsFrm]![txtBUpDate]) AND ((MatterContactsMade.Operator)=[Forms]![MattersBUpLogOptionsFrm]![txtOperator]))
ORDER BY MatterContactsMade.MatterId;
