String not being picked up in Function

Question

Im trying to add a string to a FUNCTION, but because the string contains a bracket and comma its not picking the string up.
The STRING is : Christian (non-Catholic, non-specific)
Below is the Script 
SELECT c.DESCRIPTION
, count(*)
FROM [PLATOPROD].PSAG.dbo.PICS_Bedspace_current AS p
LEFT OUTER JOIN AR_20120209_ChaplaincyPatientList AS c ON LEFT(p.[Reg No], 7) = c.IDENTIFIER collate database_default
LEFT OUTER JOIN daily_builds.dbo.Daily_WardTrans_Static w on left(c.identifier,7) = left(w.unitno, 7)
WHERE (c.ID IS NOT NULL)
AND (c.description IN (select Param from [dbo].[fn_MVParamChar](@description, ',')) OR ('Protestant' IN (select Param from [dbo].[fn_MVParamChar](@description, ','))
AND c.description IN (select Param from [dbo].[fn_MVParamChar]('Anglican,Baptist,Christian,Church of England,Church of God,''Christian (non-Catholic, non-specific)'',Methodist,Pentecostal,Presbyterian,Salvation Army,Free Church,Other Free Church', ',')) ) OR @description = 'All,')
group by c.DESCRIPTION
Below is the Function:
ALTER FUNCTION [dbo].[fn_MVParamChar]
(@RepParam varchar(8000), @Delim char(1)= ',')
RETURNS @Values TABLE (Param varchar(8000))AS
BEGIN
DECLARE @chrind INT
DECLARE @Piece varchar(8000)
SELECT @chrind = 1
WHILE @chrind > 0
BEGIN
SELECT @chrind = CHARINDEX(@Delim,@RepParam)
IF @chrind > 0
SELECT @Piece = LEFT(@RepParam,@chrind - 1)
ELSE
SELECT @Piece = @RepParam
INSERT @Values(Param) VALUES(Cast(@Piece AS varchar(100)))
SELECT @RepParam = RIGHT(@RepParam,LEN(@RepParam) - @chrind)
IF LEN(@RepParam) = 0 BREAK
END
RETURN
END

Try the below query,
SELECT c.DESCRIPTION
, count(*)
FROM [PLATOPROD].PSAG.dbo.PICS_Bedspace_current AS p
 LEFT OUTER JOIN AR_20120209_ChaplaincyPatientList AS c
  ON LEFT(p.[Reg No], 7) = c.IDENTIFIER collate database_default
 LEFT OUTER JOIN daily_builds.dbo.Daily_WardTrans_Static w
  on left(c.identifier,7) = left(w.unitno, 7)
WHERE (c.ID IS NOT NULL)
       AND (c.description IN (select Param from [dbo].[fn_MVParamChar](@description, ',')) OR
         ('Protestant' IN (select Param from [dbo].[fn_MVParamChar](@description, ','))
  AND c.description IN (select Param from
   [dbo].[fn_MVParamChar]('Anglican,Baptist,Christian,Church of England,Church of God,Methodist,Pentecostal,Presbyterian,Salvation Army,Free Church,Other Free Church', ',')
   OR c.description IN ('Christian (non-Catholic, non-specific)') ) ) OR @description = 'All,')
group by c.DESCRIPTION
