Added Two More User Parameters

I have a stored procedure that works fine in reporting services. It grabs the total of Yes's and No's by dates . But then i went ahead and added 2 more parameters to the proc, and now the totals are all wrong. I dont understand how that can mess everything up. Here is the previous stored proc, that gives the correct sum.





Code Snippet
ALTER PROCEDURE [dbo].[Testing_Questions_ALL_YESOrNO]
@Question char(80)
AS
BEGIN

SELECT
Qry_Questions.Question
, Qry_Questions.Date
, Qry_Questions.response
, B.Total
FROM Qry_Questions
INNER JOIN Qry_Sales_Group
ON dbo.Qry_Questions.sales_person_code COLLATE SQL_Latin1_General_CP1_CI_AS = dbo.Qry_Sales_Group.SalesPerson_Purchaser_Code
INNER JOIN
( Select COUNT(qq.response)as Total, Question, Date, response
FROM Qry_Questions qq
Where qq.response in ('Yes','No')
GROUP by qq.[Question] , qq.Date,qq.response ) B
ON Qry_Questions.Date = B.Date AND
Qry_Questions.Question =B.Question and
Qry_Questions.response=B.response
WHERE Qry_Questions.[Response Type]='YesNo' and Qry_Questions.Question=@Question
GROUP BY Qry_Questions.question,Qry_Questions.Date,Qry_questions.Response,B.Total
ORDER BY Qry_Questions.Question, Qry_Questions.Date


END
SET NOCOUNT OFF


Here is the edited version which only has two new parameters added to the proc. The edits are highlighted.
