It is currently grouping by StudyID not Month. Any suggestions?

Thanks!
Scott

SELECT
StudyID,
ReadingTimeInHours,
ReceiveDateTime,
MAX(ReadingTimeInHours) AS MaxReadingTime,
MIN(ReadingTimeInHours) AS MinReadingTime,
AVG(ReadingTimeInHours) AS AvgReadingTime,
Month1
FROM
(
SELECT
StudyID,
ReceiveDateTime,
DATEDIFF(hh, LocaldbView.ReceiveDateTime, LocaldbView.ReportFinalizeDT) AS ReadingTimeInHours,
DATEPART(month,LocaldbView.ReceiveDateTime) AS Month1
FROM
LocaldbView
WHERE(YEAR(LocaldbView.ReceiveDateTime) = ?)
GROUP BY
LocaldbView.ReceiveDateTime,
LocaldbView.ReportFinalizeDT,
LocaldbView.StudyID
) AS T
GROUP BY
T.Month1,T.StudyID,T.ReadingTimeInHours, T.ReceiveDateTime
