Stored Proc with SSRS multi value parameter gives " Must Declare scalar Varaiable @StateID

Question

Hi All,
I have one stored proc with @fromDate , @Todate and multivalue input
parameter@StateID of type integer.
When I run below stored proc via SSRS by selecting multiple values thru multiValue parameter into @StateID...it gives error saying "Must Declare scalar variable @StateID"
Not sure what is wrong with the input parameters.
ID is Integer type in all the 3 tables - dbo.EastCities, dbo.WestCities  , dbo.Country
I need help fixing this  "Must Declare scalar variable @StateID" error
This is the UDF split() I am using..
Function:
CREATE FUNCTION dbo.SplitStateID
(    @List VARCHAR(MAX))
RETURNS TABLE
AS   
RETURN   
(        SELECT DISTINCT [Value] = CONVERT(INT, LTRIM(RTRIM(CONVERT( VARCHAR(12),SUBSTRING(@List, Number, CHARINDEX(',', @List + ',', Number) - Number))))
 FROM  dbo.Numbers       
 WHERE Number <= CONVERT(INT, LEN(@List))AND SUBSTRING(',' + @List, Number, 1) = ','    );
 GO
 SELECT [Value] FROM dbo.SplitStateID('10,30,50');
Also, I have created dbo.Numbers table which is used in udf..

SET NOCOUNT ON;
DECLARE @UpperLimit INT;
SET @UpperLimit = 10000;
WITH n AS(   
SELECT        rn = ROW_NUMBER() OVER        (ORDER BY s1.[object_id])   
FROM sys.objects AS s1   
CROSS JOIN sys.objects AS s2   
CROSS JOIN sys.objects AS s3)
SELECT [Number] = rn - 1
INTO dbo.Numbers FROM n
WHERE rn <= @UpperLimit + 1;
CREATE UNIQUE CLUSTERED INDEX n ON dbo.Numbers([Number]);
Stored procedure:
Create Procedure dbo.CountrySelection
( @FromDate Date, @ToDate Date, @StateID Int)
AS
BEGIN
set nocount on;
SELECT * INTO #EastCities
FROM (
SELECT ID,Description from dbo.EastCities
Where ID IN (SELECT Value from dbo.SplitStateID(@StateID))
) AS A
SELECT * INTO #WestCities
FROM (
SELECT ID,Description from dbo.WestCities
Where ID IN (SELECT Value from dbo.SplitStateID(@StateID))
) AS B
SELECT * INTO #Country
FROM (
SELECT ID , Description, State,Country From dbo.Country
) AS C
SELECT EC.ID AS East, WC.ID AS West , EC.Description AS EastDesc, WC.Description AS WestDesc, CT.State, CT.Country
FROM #Country CT
LEFT JOIN #EastCities EC ON CT.ID=EC.ID
LEFT JOIN #WestCities WC ON CT.ID=WC.ID
DROP TABLE #EastCities
DROP TABLE #WestCities
DROP TABLE #Country
END
Above 3 temp tables are joined by #Country.ID key
It works fine when single value is passed in @StateID
Exec dbo.CountrySelection '01/01/2010','02/01/2010',10
It fails when multi value passed into @StateID
Exec dbo.CountrySelection '01/01/2010','02/01/2010','10,30,40'
SSRS error log shows "Must declare scalar variable @StateID"
Need help in fixing this issue.
Thanks,

Visakh,
I changed @StateID date type to varchar(max) and still I get this error.  
System.Data.SqlClient.SqlException: Must declare the scalar variable "@StateID".
   at System.Data.SqlClient.SqlConnection.OnError(SqlException exception, Boolean breakConnection)
   at System.Data.SqlClient.TdsParser.ThrowExceptionAndWarning(TdsParserStateObject stateObj)
I am running this SO in SSRS quert Type =Text
Actually sp created on db2 database and due to some limitations I am running(via SSRS) this from different db1 database data source within the same db server. When I run this sp from SSRS query designer(edit query designer button) and pass
multivalue parameters to @StateID as 10 , 20 it works and gives expected resultset.
Thanks,
