[AccessD] FW: Query not using criteria

[Kaup, Chester]

I have a query that does not appear to be using the criteria. Below is the SQL for the query. Certain ChildPID's should be excluded but they are not being excluded. What am I missing? Thanks.

SELECT ConfigMaster.PID, Constants.SDate, ConfigMaster.ChildPID, ConfigMaster.WellName
FROM ([tbl Injectors in All Patterns and Factor] INNER JOIN ConfigMaster ON [tbl Injectors in All Patterns and Factor].PID = ConfigMaster.PID) INNER JOIN Constants ON ConfigMaster.PID = Constants.PID
WHERE (((ConfigMaster.ChildPID)<>[tbl Injectors in All Patterns and Factor]![ChildPID]))
GROUP BY ConfigMaster.PID, Constants.SDate, ConfigMaster.ChildPID, ConfigMaster.WellName
HAVING (((ConfigMaster.PID)="PAT 109-1A"));

This is what should be excluded

PID                                         ChildPID               Well_Name        Sdate                    Factor1                 Factor2

And here are the query results
