Saving record but showing an error

[Guest]

I the code that I am having the problem is listed below. The problem is that
when I go to save the record it says this message:
The changes you requested to the table were not successful because they
would create duplicate values in the index, primary key, or relationship.
Change the data in the field or fields that contain duplicate data, remove
the index, ore redefine the index to permit duplicate entries and try again.

I have checked the table to see if there is a field that does not allow
duplicates and they all do allow duplicates. It is brining up the error
message on the save statement. I check the tables to see if it is updated
and all of the information is updated except for the query
QueryAddDoneSession. Everything is placed into the tables correctly

Private Sub cmdSave_Click()
On Error GoTo Err_cmdSave_Click

save = True
'Call InterviewSession.OpenSession
' Dim sessionDate As Date

Dim qdfDone As DAO.QueryDef
Dim qdfStudyIdSSN As DAO.QueryDef
Dim qdfNextDate As DAO.QueryDef
Dim qdfRemindDate As DAO.QueryDef

If Check1 = True Then

DBEngine.BeginTrans

Set qdfDone = CurrentDb.QueryDefs("QueryAddDoneSession")
qdfDone.Parameters("newId") = Me.InterviewID
qdfDone.Parameters("newVisit") = 1
qdfDone.Execute

DBEngine.CommitTrans

Set qdfNextDate = CurrentDb.QueryDefs("QueryAddStatusNextDate")
qdfNextDate.Parameters("newId") = InterviewID
qdfNextDate.Parameters("newVisit") = 2 'schedule next interview
qdfNextDate.Parameters("newInterviewDate") = date + 112
qdfNextDate.Execute

qdfNextDate.Close

Set qdfRemindDate = CurrentDb.QueryDefs("UpdateReminderDate")
qdfRemindDate.Parameters("newId") = InterviewID
qdfRemindDate.Parameters("newVisit") = 1
qdfRemindDate.Parameters("newCallDate") = date + 90
qdfRemindDate.Execute

qdfRemindDate.Close



DoCmd.DoMenuItem acFormBar, acRecordsMenu, acSaveRecord, , acMenuVer70
save = False
Call InterviewSession.CloseSession
End If

Form.Requery

Exit_cmdSave_Click:
Exit Sub

Err_cmdSave_Click:
MsgBox Err.Description
Resume Exit_cmdSave_Click

End Sub

Have you checked the actual index list in each of your tables that are in
your "QueryAddDone Session"? BTW, there should be a unique index (primary
key) for each one of them.

Not sure what your app does, but it looks like a lot of code to increment
two dates. Have you considered just using two calculated fields, and not
storing any of these?
