SQL Server 2005 Table-Valued Function Problem

I have created the below function to get a full description for a field from a table in my database.  However, when using my function, I get an error message that says:

"Cannot find either collumn "dbo" or the user-defined function or aggregate "dbo.getCode", or the name is ambiguous."

I don't know a whole lot about these functions, so I may be doing something wrong, but below is what I am executing in my query:

SELECT     dbo.getCode(grade, 'grades') AS Code
FROM         dwellings


And this is my function:

USE [MyDB]
GO
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
ALTER FUNCTION [dbo].[getCode]
(      
@Code char(20),
@CodeType char(20)
)
RETURNS TABLE
AS
RETURN
(
SELECT tbl_element_desc FROM codes_table WHERE tbl_type_code = '@CodeType' AND tbl_element = '@Code'
)



Thanks in advance for the help!

you created a table function, and not value function. please try below code.
note: you also had '@parameter' instead of @parameter




USE [MyDB]
GO
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
ALTER FUNCTION [dbo].[getCode] 
(      
@Code char(20),
@CodeType char(20)
)
RETURNS VARCHAR(200)
AS
RETURN 
(
SELECT TOP 1 tbl_element_desc FROM codes_table WHERE tbl_type_code = @CodeType AND tbl_element = @Code
)

Thanks for the quick response.  I am getting the following error now:

Msg 102, Level 15, State 31, Procedure getCode, Line 8
Incorrect syntax near 'RETURN'.

sorry, we need to add BEGIN ... END

USE [MyDB]
GO
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
ALTER FUNCTION [dbo].[getCode] 
(      
@Code char(20),
@CodeType char(20)
)
RETURNS VARCHAR(200)
AS
BEGIN
RETURN 
(
SELECT TOP 1 tbl_element_desc FROM codes_table WHERE tbl_type_code = @CodeType AND tbl_element = @Code
)
END
