Need SQL Help

I have following query which is joining couple of tables. i have a field "Status" in MeetingAttendees table. I have to add one more check (probably one more case statement) that if MA.Status=4 then Count(A.AttendeeID) as NoofAttendees. So NoofRSVPs (doesn't matter what is the status in MeetingAttendees table) will return total RSVPs and NoofAttendee will return only # of Attendees. how can i add do that? please help...

SELECT

M.State AS MeetingState,

CASE
WHEN MA.AttendeeType = 1 THEN 'Participant'
WHEN MA.AttendeeType = 2 THEN 'Speaker/Faculty'
WHEN MA.AttendeeType = 3 THEN 'Client'
WHEN MA.AttendeeType = 4 THEN 'Staff'
END AS AttendeeType,

Count(A.AttendeeID) as NoofRSVPs

FROM
Programs P
INNER
JOIN eCDReservations M
ON P.SubCompanyCode = M.SubCompanyCode
AND P.ProgramCode = M.ProgramCode
left outer
JOIN MeetingAttendees MA
ON M.ReservationID = MA.MeetingID
left outer
JOIN Attendees A
ON MA.AttendeeID = A.AttendeeID
left outer
JOIN Regions R
ON MA.RegionCode = R.RegionCode
WHERE
P.SubCompanyCode = @.SubCompanyCode AND
P.ProgramCode = @.ProgramCode




GROUP BY

M.State,

MA.AttendeeType

ORDER BY

MA.AttendeeTypeCOUNT(CASE WHEN MA.Status=4 THEN 'present' END) as NoofAttendees
