Weird Error Message in dot net

[dummy_pmgr]

Hi everyone,



I keep getting the following error. What I am trying to do is just get identity from database. I tried so many ways and wasted the whole day. I have written the snippet of sp and c#.

Please someone help me

Formal parameter '@QuestionnaireDescription' was defined as OUTPUT but the actual parameter not declared OUTPUT


This is the stored procedure which gives identity as OUTPUT

Create PROCEDURE InsertQuestionAndGetQuestionID
@QuestionName VARCHAR(2000),
@QuestionTitle VARCHAR(2000),
@QuestionDescription VARCHAR(5000),
@GetOutPut INT OUTPUT

as
--SET NOCOUNT ON
DECLARE @NewQuestionID INT



INSERT INTO dbo.Questions
(
	QuestionName,
	QuestionTitle,
	QuestionDescription
)
VALUES
(
	@QuestionName,
	@QuestionTitle,
	@QuestionDescription
)


SET @NewQuestionID = @@Identity


BEGIN
	

		IF @NewQuestion > 0
			BEGIN 
				SELECT @GetOutPut = @NewQuestionID
			END
		ELSE
			BEGIN
				SELECT @GetOutPut = 0
			END

		
	
END


and c# method which uses the above stored procedure.........


	public int InsertQuestionAndGetIdentity(string questionName, string questionTitle, string questionDescription)
		{
			int questionId;
			SqlConnection connection = this.GetConnection();
			SqlCommand sqlCommand = new SqlCommand("InsertQuestionAndGetQuestionID",connection);
			sqlCommand.CommandType= CommandType.StoredProcedure;
			SqlParameter sqlInsertParameter;
			sqlInsertParameter = sqlCommand.Parameters.Add(new SqlParameter("@QuestionName",SqlDbType.VarChar,2000));
			sqlInsertParameter.Value = questionName;
			sqlInsertParameter = sqlCommand.Parameters.Add(new SqlParameter("@QuestionTitle",SqlDbType.VarChar, 2000));
			sqlInsertParameter.Value = questionTitle;
			sqlInsertParameter = sqlCommand.Parameters.Add(new SqlParameter("@QuestionDescription",SqlDbType.VarChar,5000));
			sqlInsertParameter.Value = questionDescription;
			sqlInsertParameter.Value = sqlCommand.Parameters.Add(new SqlParameter("@GetOutPut",SqlDbType.Int));
			sqlInsertParameter.Direction = ParameterDirection.Output;
            sqlInsertParameter.Value = 0;
			
			try
			{
				connection.Open();
				sqlCommand.ExecuteNonQuery();
				questionId = Convert.ToInt16(sqlInsertParameter.Value);
				return questionId;


			}
			catch(Exception exception)
			{
				throw exception;

			}
			finally
			{
				connection.Close();

			}

		}
