Quote Prob

I have a stored proc that creates a view so I can pass parameters. I need to replace the 120 with the variable @MEA. I can't get my quotes right to make this work.
ALTER PROCEDURE dbo.spi_CallList
(@strAgent nchar(4), @MEA int)

AS

DECLARE @Msg varchar(255)
declare @SQL varchar(4000)

IF EXISTS (SELECT TABLE_NAME FROM INFORMATION_SCHEMA.VIEWS WHERE TABLE_NAME = 'qs_CallList1')
DROP VIEW qs_CallList1

SET @SQL = 'Create view qs_CallList1 as
SELECT top 100 percent tsd_Claim.clinsnum AS [Ins#], Sum(tsd_Claim.cloutstandingamt) AS OutstndByIns
FROM (tsd_Claim LEFT JOIN [qs_SQLClaimStatusLastEntryCL] ON (tsd_Claim.clnum = [qs_SQLClaimStatusLastEntryCL].Claim)
AND (tsd_Claim.clpid = [qs_SQLClaimStatusLastEntryCL].Pat))
LEFT JOIN tsd_Patient ON tsd_Claim.clpid = tsd_Patient.PID
WHERE (((tsd_Patient.PAGENT)=''' + ltrim(rtrim(@strAgent)) + ''')
AND (([qs_SQLClaimStatusLastEntryCL].Pat) Is Null)
AND ((tsd_Claim.clfromdos)<GetDate()-120))
GROUP BY tsd_Claim.clinsnum
ORDER BY Sum(tsd_Claim.cloutstandingamt) DESC'
EXECUTE(@sql)
