Modules & VBA :: Calling Stored Procedure With Parameters

I have code for calling stored procedure with parameters,which is as follows

Dim qdf As DAO.QueryDef, rst As DAO.Recordset
Dim IdValueToProcess As Long

IdValueToProcess = 221177 ' test data
Debug.Print (IdValueToProcess)
Set qdf = CurrentDb.CreateQueryDef("")

[Code] ....

And my stored procedure is

Code:
ALTER PROCEDURE [dbo].[spItemDesc]
@ItemNo varchar(200) ,
AS
BEGIN
set nocount on ;
select ProductDesc1,ProductDesc2 from ProductDatabase.dbo.tblProductInfo where ProductNumber = @ItemNo
END

The error comes on debug.print(rst!ProductDesc1)

And it says "Item not found in the collection"
