nested select statement help

I am having trouble displaying the number of opencases that are found in my stored procedure, I am not sure if that select statement is placed properly.

    BEGIN
    -- SET NOCOUNT ON added to prevent extra result sets from
    -- interfering with SELECT statements.
    SET NOCOUNT ON;
    -- Insert statements for procedure here
    SELECT
           C.CaseNumber
,          O.OfficeName
,          CT.Description AS CaseType,
           C.DateOpened AS DateOpened,
           CR.Description AS Court
FROM 
(

       SELECT C.CaseId, O.OfficeId FROM [Case] C
       INNER JOIN [Appointment] A ON C.CaseId = A.CaseId
       INNER JOIN [Office] O ON A.OfficeId = O.OfficeId,
       (
           SELECT COUNT(DISTINCT CD.CaseId)
           FROM [Case] CD
            INNER JOIN CaseOffice COD ON CD.CaseId = COD.CaseId
            INNER JOIN Office OD ON COD.OfficeId = OD.OfficeId
            LEFT OUTER JOIN CaseStatusChange CSC ON CD.CaseId = CSC.CaseId
           WHERE OD.OfficeId = O.OfficeId
           AND
           ( CD.DateOpened BETWEEN @BeginDate AND @EndDate 
                OR
             CSC.DateReopened BETWEEN @BeginDate AND @EndDate
            )
        )AS OpenCases

       WHERE 
       -- Case was open (or reopened) during the date range 
       C.DateOpened BETWEEN @beginDate AND @endDate 
       OR 
       C.CaseId IN (SELECT CaseId FROM CaseStatusChange WHERE DateReopened BETWEEN @beginDate AND @endDate)
       AND 
       -- Office had an appointment sometime during the date range
       A.DateOn < @endDate AND (A.DateOff IS NULL OR A.DateOff BETWEEN @beginDate AND @endDate)

       GROUP BY C.CaseId, O.OfficeId
) 

CaseOfficeAppointment
INNER JOIN [Case] C ON CaseOfficeAppointment.CaseId = C.CaseId
INNER JOIN [Office] O ON 开发者_开发知识库CaseOfficeAppointment.OfficeId = O.OfficeId
INNER JOIN [CaseType] CT ON C.CaseTypeId = CT.CaseTypeId
INNER JOIN [Court] CR ON C.CourtId = CR.CourtId

OpenCases should occur before the Join statements as OpenCases is a data Column
