SQL Server stored procedure error on INSERT - sql-server-2008

Question

I have a simple stored procedure for INSERT, lately I noticed I am getting unusual errors one doesn't seems to be like one
I get following error when I try to compile the following stored procedure:
Msg 137, Level 15, State 2, Procedure usp_AddArticleCategory, Line 15
Must declare the scalar variable "#ArtcileCategoryActive".
This is my code:
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
-- =============================================
-- =============================================
CREATE PROCEDURE [dbo].[usp_AddArticleCategory]
#ArticleCategoryName nvarchar(200),
#LangID int,
#ArticleCategoryActive bit,
#Type nvarchar(100)
AS
SET NOCOUNT ON;
BEGIN
INSERT INTO art_Category (ArticleCategoryName,[LangID],ArtcileCategoryActive,[Type])
VALUES (#ArticleCategoryName, #LangID, #ArtcileCategoryActive, #Type)
END
Table structure:
CREATE TABLE [dbo].[art_Category](
[ArticleCategoryID] [int] IDENTITY(1,1) NOT NULL,
[ArticleCategoryName] [nvarchar](200) NULL,
[LangID] [int] NULL,
[ArtcileCategoryActive] [bit] NULL,
[Type] [nvarchar](100) NULL,
CONSTRAINT [PK_art_Category] PRIMARY KEY CLUSTERED
(
[ArticleCategoryID] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
) ON [PRIMARY]
I compared table columns, datatypes but I am not sure why this error keeps coming.
Appreciate help with this

Answer 1

You're declaring;
ArticleCategoryActive
and using;
ArtcileCategoryActive
Spot the difference? :)
