Use Multiple Varchar as a parameter - sql-server-2008

Question

I am trying to create a query that will allow me to use multiple VarChars as a parameter in SSRS.
Here's the code:
Declare #CallCodes as VarChar(10)
Set #CallCodes = ('MORC30' , 'Morc60')
;
With Data
AS
(SELECT
VC.[CallCode]
,VC.[HospCode]
,VC.[HospMastID]
,VC.[ClientID]
,Row_Number () Over (Partition By HospMastID, VC.ClientID Order By HospMastID, VC.ClientID, GLCode) as Txn
FROM
[RptSys].[dbo].[CSC_VuesionImport_DevDetl] as VC
Inner Join
[AVimark_OLTP].[dbo].[Client] as C
on
VC.HospMastID = C.HospitalMasterID
and
VC.ClientID = C.ClientID
Inner Join
[Avimark_OLTP].[dbo].[Patient] as P
on
VC.HospMastID = P.HospitalMasterID
and
VC.PatientID = P.PatientID
Inner Join
[Avimark_OLTP].[dbo].[Treatment] as T
on
VC.HospMastID = T.HospitalMasterID
and
VC.MastReminder = T.Code
Where
VC.CallCode in #CallCodes)
This gives an error when I try to run it. The final output is to allow the end user to choose from a drop down list in an SSRS report I have tried all variations of in or like for the where statement.
Any suggestions would be greatly appreciated.

Why don't you take the Parmaeter in a temporary table marked with #
CREATE TABLE #tmp(
Callcodes varchar(10))
INSERT INTO #tmp
VALUES
('MORC30'),
('Morc60')
With Data
AS
(SELECT
VC.[CallCode]
,VC.[HospCode]
,VC.[HospMastID]
,VC.[ClientID]
,Row_Number () Over (Partition By HospMastID, VC.ClientID Order By HospMastID, VC.ClientID, GLCode) as Txn
FROM
[RptSys].[dbo].[CSC_VuesionImport_DevDetl] as VC
Inner Join
[AVimark_OLTP].[dbo].[Client] as C
on
VC.HospMastID = C.HospitalMasterID
and
VC.ClientID = C.ClientID
Inner Join
[Avimark_OLTP].[dbo].[Patient] as P
on
VC.HospMastID = P.HospitalMasterID
and
VC.PatientID = P.PatientID
Inner Join
[Avimark_OLTP].[dbo].[Treatment] as T
on
VC.HospMastID = T.HospitalMasterID
and
VC.MastReminder = T.Code
Where
VC.CallCode in (SELECT * FROM #tmp))
I hope this is what you are looking for, if not please tell me. Or like mentioned in the comments give a error message
