Results Column Null from Stored Procedure

Within my stored procedure i am checking for open cases within a date range and also for open cases based only on the begin date and before the begin date. I tried to add all the selects into one stored procedure but when i execute the code - for the open cases on begin date all the results returned are null. Here is my full stored procedure and the select statement AS OpenBeginCases is where i am running into trouble.

 SELECT
       C.CaseNumber,
       O.OfficeName,
       CT.Description AS CaseType,
       DATEADD(dd, 0, DATEDIFF(dd, 0, C.DateOpened)) AS DateOpened,
       CR.Description AS Court,
       CaseOfficeAppointment.OpenCases,
       CaseOfficeAppointment.CloseCases,
       CaseOfficeAppointment.OpenBeginCases

       SELECT  C.CaseId, O.OfficeId, CRT.CourtId,

Try to clean up your script into CTE format for clarity, perhaps you'll get a better insight after that.

hmmm... wild stab in the dark.... change your UNION to a UNION ALL?

No nevermind that won't matter.
