Dear All,

I have a question about using the Count function.  I'm trying to count the number of records in Field 4 for each combination of field1, field 2 and field3.

The input table -

The output I'm looking for-

Desired Output
Below is my query it seems to counting the number of records in field 4 and assigning it to field2, instead of breaking it down according to field3.    

SELECT [LocationData].Field1, Count([LocationData]. Field4) AS Field4_Count, MonitoredData.Field2, MonitoredData.Field3
FROM [LocationData] INNER JOIN MonitoredData ON [LocationData].Field2 = MonitoredData.Field2
GROUP BY [LocationData].Field1, MonitoredData.Field2, MonitoredData.Field3
HAVING ((([LocationData].Field1) Is Not Null));

Open in new window


I thought the names would make it easier to explain now I don't think so!

Thanks
