Report Parameter

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. I just want to know what im doing wrong, that the totals are completely off now. Did i set up the parameter wrong in reporting services. I have the 3 parameters list in the report parameter section, and even have them cascading off of each other. That seems to work fine. but for the first matrix in my report, but the second matrix with this stored proc, is way off. Please help!!.





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.
