[AccessD] Calculation in query problem

Dunno...the Where clause was not being utilized properly for one thing.
This will run much more efficiently....
I couldn't really pin-point the problem though.

SELECT [tbl Produced Gas Meters].Meter_ID,
       scada_V_All_Meter_Volumes.ReadingDate,
       [Volume] * 1000      AS Mcf,
       Sum([Volume]) * 1000 AS McfTest
FROM   (([tbl Produced Gas Meters]
         INNER JOIN scada_Gas_Meter_Master
           ON [tbl Produced Gas Meters].Meter_ID =
scada_Gas_Meter_Master.Meter_ID)
        INNER JOIN ([qry Last Gas Analysis Date]
                    INNER JOIN (GA_Header
                                INNER JOIN GA_Details
                                  ON GA_Header.ID = GA_Details.HEADER)
                      ON ( [qry Last Gas Analysis Date].MaxOfSample_Date =
GA_Header.Sample_Date )
                         AND ( [qry Last Gas Analysis Date].METER =
GA_Header.METER ))
          ON [tbl Produced Gas Meters].[Meter_ID Text] = GA_Header.METER)
       INNER JOIN scada_V_All_Meter_Volumes
       ON scada_Gas_Meter_Master.Tagname = scada_V_All_Meter_Volumes.Tagname
WHERE  (GA_Details.UNIT = "PCT" ) AND ([tbl Produced Gas Meters].Meter_ID )
= 362915) AND
       ( scada_V_All_Meter_Volumes.ReadingDate  = #12 / 1 / 2011 # )

GROUP  BY [tbl Produced Gas Meters].Meter_ID,
          scada_V_All_Meter_Volumes.ReadingDate,
          [Volume] * 1000
ORDER  BY scada_V_All_Meter_Volumes.ReadingDate;
