Having Difficulty Creating A Stored Procedure

I am trying to create stored procedure i Query analyzer in visual studio 2005. I am having
difficulty though. Whenever I press the execute button, here is the error message I get:

Msg 102, Level 15, State 1, Procedure MarketCreate, Line 21
Incorrect syntax near 'MarketName'.


Here is the stored procedure. Note that the very first column in named "MarketId" but I did not
include it in the stored procedure since it should be auto generated.


USE [StockWatch]
GO
/****** Object:  StoredProcedure [dbo].[MarketCreate]    Script Date: 08/28/2007 15:49:26 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO


CREATE PROCEDURE [dbo].[MarketCreate]

(
  @MarketCode   nvarchar(20),
  @MarketName   nvarchar(100),
  @LastUpdateDate  nvarchar(2),
  @MarketDescription  nvarchar(100)
)

AS
INSERT INTO Market
(
  MarketCode
  MarketName
  LastUpdateDate
  MarketDescription
)
VALUES
(
  @MarketCode
  @MarketName
  @LastUpdateUser
  @MarketDescription
)
