Procedure or Function - Too Many Argument

GameSecretary.Com is up and running, but now I am working on the Administrative side. One of the features I wanted to add was the ability to easily edit game's information. So I dropped a DetailsView onto a page, bound it to my database and began viewing the events. But when I click update it gives me a "Procedure or function EditGame has too many arguments specified." EditGame is the name of my stored procedure. But I can't find anything wrong with my code. Here is the page code:
<%@ Page Language="VB" MasterPageFile="~/Admin.master" AutoEventWireup="false" CodeFile="EditDetailGames.aspx.vb" Inherits="Admin_EditDetailGames" title="Untitled Page" %>
<asp:Content ID="Content1" ContentPlaceHolderID="ContentPlaceHolder1" Runat="Server">

   UpdateCommand="UPDATE Game SET [Title] = @Title, [Popularity] = @Popularity, [Description] = @Description, [Dangers] = @Dangers, [Variants] = @Variants, [Source] = @Source, [Type] = @Type, [Approved] = @Approved WHERE ID=@ID">

Here is my stored procedure code:
ALTER PROCEDURE dbo.EditGame
    (
    @ID as int,
    @Title as varchar(200),
    @Popularity as int,
    @Description as varchar(8000),
    @Dangers as varchar(8000),
    @Variants as varchar(8000),
    @Source as varchar(500),
    @Type as int,
    @Approved as int
    )
AS
    UPDATE Game SET Title = @Title, Popularity = @Popularity, Description = @Description, Dangers = @Danger
