How to run a function and put its result into a variable?

Question

SQL

CREATE FUNCTION GetConfigID @CL ID INT
RETURNS INT AS
BEGIN
  DECLARE @SConfigIdID INT
  SET @SConfigIdID = (SELECT ConC. ID FROM tblContract CN
    INNER JOIN tblClient CL ON CN.CLIENT_ID = CL.ID INNER JOIN tblCar CR ON CN.CAR_ID = CR.ID
    INNER JOIN tblConfigCar ConC ON CR.CONFIG_MODEL_ID = ConC. ID WHERE Cl.ID = @CL_ID)

RETURN @ConfigldID
END
GO

Is there a function, how to run it, so that the result is placed in a variable?
