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.

GROUP BY Qry_Questions.question,Qry_Questions.Date,Qry_questions.Response,B.Total

SET NOCOUNT OFF

Try this:

AND (@.Region_Key is null or REGION_KEY=@.Region_Key)
