Grouping By Week In Stored Procedure

Hi all,

I am using the below statement to get some dates grouped by date, in my SP. 

SELECT TOP 100 PERCENT COUNT(dbo.test.CallDate) AS CallCount, year(dbo.test.CallDate) AS CallYear, datepart(wk, dbo.test.CallDate) AS [Week]
FROM dbo.test

LEFT OUTER JOIN dbo.view1 ON dbo.test.CallID = dbo.view1.CallID
LEFT OUTER JOIN dbo.view2 ON dbo.test.CallID = dbo.view2.CallID

WHERE (dbo.view1.[ACCOUNT ID] = @accountid

OR (dbo.view2.[ACCOUNT ID] = @accountid

AND (convert(varchar(10),dbo.test.CallDate,121) BETWEEN CONVERT(DATETIME, @StartDate, 102)AND CONVERT(DATETIME, @EndDate, 102))
GROUP BY year(dbo.test.CallDate), datepart(wk, dbo.test.CallDate)
ORDER BY year(dbo.test.CallDate), datepart(wk, dbo.test.CallDate)

i gave startdate as 1/1/2007 and endDate as 2/18/2007

i am getting the reuslt as
count year week
42 2001 32
2 2001 39
1 2001 51
1 2002 17
1 2002 19
106 2002 21
183 2002 22
226 2002 23
.................................
...................................
1208 2007 1
1292 2007 2

actually i should get only the last 2 rows.
Can anyone  please point out, why i am getting the 2001, 2002 data? and how to fix that?

Thanks
