Cross Tab Query Help needed

[john12345]

I have a made a crosstab query in access which is causing me some heartache. The query works fine until I try and introduce an extra field as a row heading and group by. The field is “fldEquipmentType”.
The query actually runs, but then gives me an error of : “Datatype mismatch in criteria expression”.
A dialogbox comes up with the error message and when I press OK every cell in the query becomes “#Name?”

The SQL for the query is:


PARAMETERS [Forms]![frmReportDatesDialogBox]![BeginningDate] DateTime, [Forms]![frmReportDatesDialogBox]![EndingDate] DateTime;
TRANSFORM [fldPower]*Format(Count([fldStatusCode]),"0&quot AS TotalPower
SELECT [qryUtilisation&EquipmentCodesAllDepotsOnly].fldEquipmentType, [qryUtilisation&EquipmentCodesAllDepotsOnly].fldPower, Format(Avg([TotalPower]),"0.0&quot AS Average
FROM [qryUtilisation&EquipmentCodesAllDepotsOnly]
GROUP BY [qryUtilisation&EquipmentCodesAllDepotsOnly].fldEquipmentType, [qryUtilisation&EquipmentCodesAllDepotsOnly].fldPower
ORDER BY [qryUtilisation&EquipmentCodesAllDepotsOnly].fldPower
PIVOT Format([fldDate],"ddd&quot In ("Sun","Mon","Tue","Wed","Thu","Fri","Sat"


Please Note: the parameters are required to run the base query “qryUtilisation&EquipmentCodesAllDepotsOnly”

Can anyone suggest what is wrong?
Any help greatly appreciated.
