Stored Procedure och Insert

Jag har följande kod:

CREATE PROCEDURE sp_InsertSupportQ
	@subject (char) (255),
	@message (text),
	@date (datetime),
	@from (char) (100),
	@name (char) (100),
	@username (char) (100),
	@telephone (char) (100),
	@email (char) (100),
	@uniqueid (char) (30)
AS
INSERT INTO 	SupportQ
		(Subject, Message, [Date], [From], [Name], Username, Telephone, Email, UniqueID) 
values
		(@subject, @message, @date, @from, @name, @username, @telephone, @email, @uniqueid)
GO

Must declare the variable @subject när jag försöker spara SP:n
Vad är fel?

@subject char(255),
@message text,
@date datetime,
@from char(100),
@name char(100),
@username char(100),
@telephone char(100),
@email char(100),
@uniqueid char(30)

Tack :)
