I have multiple reports with different versions (each version have different users) where I need to create drop down filters with ability to choose users whose are assigned in choosen version. I'm using following stored procedure to receive users list depending on version.

```
CREATE PROCEDURE sp_ContList
@version INT
AS
BEGIN
    SELECT [User] 
    FROM FormInstances 
    WHERE FormVersionId = @version
    GROUP BY [User]
END

```

Now I need to create drop down filter in report (*Microsoft Visual Studio 2013*) with user for example where `@version = 1`. How to pass parameter's value in SSRS correctly?
