Call stored procedure from another stored procedure?

How do I call this stored procedure:

CREATE Procedure hentSpecialPris
(
@.varenr int,
@.cvr int,
@.pris decimal(7,2) OUTPUT
)

AS

DECLARE @.antal int

SET @.antal = 0

SET @.antal = (SELECT COUNT(*) FROM rabat WHERE varenr=@.varenr and cvr = @.cvr)

IF @.antal < 1
BEGIN
SET @.pris = (SELECT pris FROM vare WHERE varenr=@.varenr)
END

ELSE
BEGIN
SET @.pris = (SELECT pris FROM rabat WHERE varenr=@.varenr and cvr = @.cvr)
END

GO

from another stored procedure?? I want to get the output value of the stored procedure?

CREATE PROCEDURE OtherProc @.varent int,@.cvr int
AS
DECLARE @.pris decimal(7,2)
EXEC hentSpecialPris @.varent,@.cvt,@.pris OUTPUT
GO

You could also make this SP a user defined funciton, if it will always be called from another SP.
