sql server/vb.net

I have some code to send some data to insert into a table but having trouble with the USP with it showing syntax error

The USP:

USE [Dictionary]
GO

SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO

ALTER PROCEDURE [dbo].[usp_InsertLinkWords]
@StrShort varchar(50),
@WordCommon varchar(50)
AS
BEGIN
INSERT INTO [dbo].[TblShortDescLink] ([StrShort], WordCommon )

SELECT [dbo].[TblWords].[StrShort], @WordCommon as WordCommon
FROM [dbo].[TblWords] 
WHERE  [dbo].[TblWords].StrShort=@StrShort
GROUP BY StrShort
END
