get a binary value using tsql

I have a Sql 2005 database with a test table containing one record. four columns (3 char and 1 varbinary(max)

If I write a query like this I get the returned record

select phrase_content from phrase_index where
application ='cs' and
phrase_number = '1' and
language = 'eng' and
gender = 'female'

Select allOpen in new window

when I write a stored procedure to pass in the input and get the output of phrase_content all I get is a null value. What am I doing wrong? Why can't I get the value of phrase_content when using a stored procedure?

ALTER PROCEDURE [dbo].[get_PhraseContent] 
	-- Add the parameters for the stored procedure here

@application char,
@phrase_number char,
@language char,
@gender char,
@phrase_content binary OUTPUT

AS
BEGIN
	-- SET NOCOUNT ON added to prevent extra result sets from
	-- interfering with SELECT statements.
	SET NOCOUNT ON;



    -- Insert statements for procedure here
	SELECT @phrase_content = phrase_content from phrase_index where 
	application = @application and
	phrase_number = @phrase_number and
	language = @language and
	gender = @gender
	
END
