Hi, i have the following SQL stored procedure. Every time i execute it, it will return me error message. Below are my codes:

SQL

DECLARE @SQL NVARCHAR(MAX)
DECLARE @params NVARCHAR(MAX)

SELECT @SQL = 'SELECT CustomerName,[0] as Pending, [1] as Save_As_Draft, [2] as Spec_Confirmed, [3] as Request_Revision, [4] as Withdraw, [5] as Pending_RND, [6] as Pending_QC, [7] as Manday_Confirmed, [0]+[1]+[2]+[3]+[4]+[5]+[6]+[7] as Total
FROM
(
    SELECT P.DocStatus,C.CustomerName,P.CustomerID, YEAR(P.CreateDate) as createYear
    FROM dbo.CRF_Project P
    INNER JOIN dbo.CustomerList C
    ON P.CustomerID = C.CustomerID
) p

PIVOT
(
    COUNT (createYear) FOR DocStatus IN ([0], [1], [2], [3], [4], [5], [6], [7])

) AS pvt '

SELECT @params = '@CUSTNAME VARCHAR(MAX),
                  @YEAR VARCHAR(MAX)'

IF(@CUSTNAME != '')
    SELECT @SQL = @SQL + ' WHERE CustomerName IN (' + @CUSTNAME + ')'
ELSE
    SELECT @SQL = @SQL
IF(@YEAR != '')
    SELECT @SQL = @SQL + ' WHERE createYear = ' +@YEAR+ '' --<-error here
ELSE
    SELECT @SQL = @SQL

EXEC sp_executesql @SQL, @params, @CUSTNAME, @YEAR
END

FIY, my input for @CUSTNAME is 'Osm' and @YEAR is '2014'
but if i leave it blank for both or input only for @CUSTNAME, it works fine, just when i input the @YEAR it will prompt me error
