Trying to run a distinct count for all ID's that have a date in february, and don't have an entry into the last 12 months.

I think I have it setup properly but the number I getting back is too high. Could someone take a peak and let me know if I am doing something wrong?

Thanks


SELECT     COUNT(DISTINCT dbo.tblContracts.ClientID) AS NumNewClients
FROM         dbo.tblContractDetail INNER JOIN
                      dbo.tblContracts ON dbo.tblContractDetail.ContractID = dbo.tblContracts.ContractID
WHERE     (dbo.tblContracts.ClientID NOT IN
                          (SELECT DISTINCT clientid
                            FROM          dbo.tblContractDetail INNER JOIN
                                                   dbo.tblContracts ON dbo.tblContractDetail.ContractID = dbo.tblContracts.ContractID
                            WHERE      tblcontractdetail.inhomedate BETWEEN DATEADD(day, - 1, '1/21/2010') AND DATEADD(month, - 12, '1/21/2010'))) AND 
                      (dbo.tblContractDetail.FranchiseID = 'mdipho') AND (MONTH(dbo.tblContractDetail.InHomeDate) = 2) AND 
                      (dbo.tblContractDetail.InHomeDate NOT BETWEEN DATEADD(day, - 1, '1/21/2010') AND DATEADD(month, - 12, '1/21/2010'))

between needs the lower value first!

No, you're never too old to Yak'n'Roll if you're too young to die.
