Listbox Only Makes Exclamation Sound

Hi All,

I have been trying to improve a form used to add/edit names in a mailing list. What I want to do is check the database for possible duplicate names and alert the user to the fact that their new person may already be in the db.

I used the following VBA code in the After Update event as follows:

Private Sub txtLastName_AfterUpdate()

On Error Resume Next
Dim strLastName As String
Dim NbrNames As Variant
Dim strNameSQL As String

txtLastName = Trim(txtLastName)
If Not Mid(txtLastName, 1, 1) = "=" Then
txtLastName = StrConv(txtLastName, vbProperCase)
Else
txtLastName = Mid(txtLastName, 2, 999)
End If

' Test for duplicate last name in data base
NbrNames = DCount("[tblMemberListings].[mlLastName]", "tblMemberListings", "[tblMemberListings].[mlLastName]= '" & txtLastName & " '")
If NbrNames > 0 Then
strNameSQL = "SELECT ALL tblMemberListings.mlID, tblMemberListings.mlLastName, tblMemberListings.mlFirstName, tblMemberListings.mlSpouseSO, tblMemberListings.mlAddress " & _
"FROM tblMemberListings " & _
"WHERE ((tblMemberListings.mlLastName) LIKE '" & txtLastName & "*') " & _
"ORDER BY tblMemberListings.mlLastName, tblMemberListings.mlFirstName, tblMemberListings.mlSpouseSO;"
lstDuplicateNames.RowSource = strNameSQL
Beep
lstDuplicateNames.Visible = True

End If


End Sub

This generates a useful list of potential persons already in the db. The user then has the choice of continuing to add the new name and address or they should be able to select one of the names in the listbox and refresh the form with that person's data for possible modification.

I currently have these two Event Procedures in place:

Private Sub lstDuplicateNames_AfterUpdate()
On Error Resume Next
'MsgBox "Sub lstDuplicateNames_Click value = " & lstDuplicateNames.Column(0)

If Not IsNull(lstDuplicateNames.Column(0)) Then
' User chooses and existing record
Me.RecordsetClone.FindFirst "[mlID] = " & lstDuplicateNames.Column(0)
If Not Me.RecordsetClone.NoMatch Then
Me.Bookmark = Me.RecordsetClone.Bookmark
End If
Me.lstDuplicateNames.Visible = False
Me.Refresh
End If

End Sub

and

Private Sub lstDuplicateNames_Click()
Me.txtHidden.SetFocus
Me.lstDuplicateNames.Visible = False

End Sub

The problem is that when one clicks on one of the listed names just two things happen:

1 - a fine dotted box outline appears around the *first* record in the listbox
2 - the MS Exclamation wav sound is generated each time the mouse button is clicked. :confused:

Short of enrolling in a local junior college that offers Access 101 what can I do to get this addition working? I'm also not sure that my code to refresh the form is going to work, but right now I don't ever get there. ;)

Oh, this problem is occurring in MS Access 2000.

Any help would be greatly appreciated by this NOOB.
