Aaargh! Storedproc Vs SQL In Gridview Update

When I attempt to update using a stored procedure I get the error 'Incorrect syntax near sp_upd_Track_1'. The stored procedure looks like the following when modified in SQLServer:

ALTER PROCEDURE [dbo].[sp_upd_CDTrack_1]

(@CDTrackName nvarchar(50),

@CDArtistKey smallint,

@CDTitleKey smallint,

@CDTrackKey smallint)

AS

BEGIN



SET NOCOUNT ON;

UPDATE [Demo1].[dbo].[CDTrack]

SET [CDTrack].[CDTrackName] = @CDTrackName

WHERE [CDTrack].[CDArtistKey] = @CDArtistKey

AND [CDTrack].[CDTitleKey] = @CDTitleKey

AND [CDTrack].[CDTrackKey] = @CDTrackKey

END

But when I use the following SQL coded in the gridview updatecommand it works:


       
"UPDATE [Demo1].[dbo].[CDTrack]


   SET [CDTrack].[CDTrackName] = @CDTrackName


 WHERE [CDTrack].[CDArtistKey] = @CDArtistKey


   AND [CDTrack].[CDTitleKey]
  = @CDTitleKey



   AND [CDTrack].[CDTrackKey]
  = @CDTrackKey"

Whats the difference? The storedproc executes ok in sql server and I guess that as the SQL version works all of my databinds are correct. Any ideas, thanks, James.
