Exclude records if two fields are null

I am using Access as a front end for SQL Server in this case.  Below is the current query that I need to add the following criteria:
I need to exclude records from the result set if both the dbo.Membership_20060411.Phone AS ULTRAPhone and dbo.qryUnionNetMemberInfo.DispatchPhone fields are null.  If either phone number exists I need the record to appear.

SELECT     dbo.Membership_20060411.Member_ID, dbo.Membership_20060411.First_Name, dbo.Membership_20060411.Last_Name,
                      dbo.Membership_20060411.Zip_Postal, dbo.Membership_20060411.State_Prov, dbo.Membership_20060411.Class,
                      dbo.qryUnionNetMemberInfo.RegisteredVoter, dbo.qryUnionNetMemberInfo.RegisteredVoterDate, dbo.Membership_20060411.Phone AS ULTRAPhone,
                      dbo.qryUnionNetMemberInfo.DispatchPhone, dbo.Membership_20060411.County, dbo.tblCounty.Cluster
FROM         dbo.Membership_20060411 INNER JOIN
                      dbo.tblCounty ON dbo.Membership_20060411.County = dbo.tblCounty.County LEFT OUTER JOIN
                      dbo.qryUnionNetMemberInfo ON dbo.Membership_20060411.Member_ID = dbo.qryUnionNetMemberInfo.UBCNumber LEFT OUTER JOIN
                      dbo.qrySOURCE_RegisteredVoters_AllPhones ON
                      dbo.Membership_20060411.Member_ID = dbo.qrySOURCE_RegisteredVoters_AllPhones.MEMBER_ID
WHERE     (dbo.qrySOURCE_RegisteredVoters_AllPhones.MEMBER_ID IS NULL) AND (dbo.Membership_20060411.State_Prov = N'CA') AND
                      (NOT (dbo.tblCounty.Cluster IS NULL))

Try this:

Where (nz(dbo.qrySOURCE_RegisteredVoters_AllPhones.MEMBER_ID,"") = "") AND (dbo.Membership_20060411.State_Prov = N'CA') AND
                      (NOT (nz(dbo.tblCounty.Cluster ,"")= ""))


Where (nz(dbo.qrySOURCE_RegisteredVoters_AllPhones.MEMBER_ID,"") = "") AND(dbo.Membership_20060411.State_Prov = N'CA') AND  (NOT (nz(dbo.tblCounty.Cluster ,"")= ""))

I think that this will cause trouble, too: dbo.Membership_20060411.State_Prov = N'CA'

WHat are you testing for here?  SHould it be:

dbo.Membership_20060411.State_Prov = 'NCA'

Create a calc'd field something like
Nz([dboMembership_2006411.Phone],"")&Nz([dbo.qryUnionNetMemberInfo.DispatchPhone],"") AS NullPhone

and set the criteria for this field to <> ""

The current WHERE statement is testing for the following:
1. Does the Member ID in dbo.Membership_20060411 exist in dbo.qrySOURCE_RegisteredVoters_AllPhones?  If so, don't include it in the results.
2. Is the State CA?  If not, exclude it.
3. Do they live in Northern California?  If not, exclude it.

So I am attempting to add one last check to see if a phone number exists in either of the phone number fields.

I would like to try the calculated field but am unsure how to execute it.  Would that statement be in the SELECT area?
omgangIT ManagerCommented:
Yes, add the statement to the Select area and then add to the WHERE clause

WHERE     (dbo.qrySOURCE_RegisteredVoters_AllPhones.MEMBER_ID IS NULL) AND (dbo.Membership_20060411.State_Prov = N'CA') AND
                      (NOT (dbo.tblCounty.Cluster IS NULL) AND (Nz([dboMembership_2006411.Phone],"")&Nz([dbo.qryUnionNetMemberInfo.DispatchPhone],""))<>""
