How Can I Stop The Totals From Multiplying

I have a db that tracks clients, payments, and clients codes. A client can be assigned many codes. In my query I'm asking to see any clients that have two selected codes and also of those show me those that have a sum of payments between 1 and 100000 dollars. The query returnes the clients with the selected codes, but the total payments is multiplied by the number of the codes they have of the ones that I select. In this case 'email group' or 'member'

So if a client had a total of $20,000 dollars in payments and they had both of the codes I selected the sum of payments is returned as $40,000.

Any thoughts are appreciated!

Here is a sample example:

SELECT DISTINCT
[Salutation], [Client_ID] AS 'Client ID', SUM([dbo].[vw_ClientTotals].[Total Payments]) AS 'Sum(Total Payments)'
FROM [dbo].[All_Constituents]
INNER JOIN [dbo].[tblClientCodes] ON [dbo].[tblClientCodes].[Client_ID]=[dbo].[All_Constituents].[Client_ID]
INNER JOIN [dbo].[tblClientCodeLookUp] ON [dbo].[tblClientCodeLookUp].[ClientCode_ID]=[dbo].[tblClientCodes].[ClientCodeLookup_ID]
INNER JOIN [dbo].[vw_ClientGiftTotals] ON [dbo].[vw_ClientGiftTotals].[Client_ID]=[dbo].[All_Constituents].[Client_ID]
WHERE ( ([dbo].[tblClientCodeLookUp].[ClientCode] = 'Member') OR ([dbo].[tblClientCodeLookUp].[ClientCode] = 'Email Groups') )
GROUP BY [dbo].[All_Constituents].[Salutation], [dbo].[All_Constituents].[Client_ID]
HAVING  (SUM([dbo].[vw_ClientTotals].[TotalPayments]) BETWEEN '1' AND '100000')
