DLookup Searching

I have a database that has some tables joined via relationships.
The main table is a customer table, for gathering the first name, last name, address, etc. Then there are others are linked to it.
I have worked up a DLookup command

On Error GoTo ErrorHandler
Dim varFound As Variant
varFound = DLookup("LastName", "tblCustomers", "LastName = '" & Me.txtLastName & "' AND FirstName = '" & Me.txtFirstName & "'")

If Not IsNull(varFound) Then
Dim Msg, Style, Title, Help, Ctxt, Response, MyString
Msg = "There is a Duplicate Record found. Are you sure you want to continue ?" ' Define message.
Style = vbYesNo + vbCritical + vbDefaultButton2 ' Define buttons.
Title = "Duplicate Record Found" ' Define title.
Help = "DEMO.HLP" ' Define Help file.
Ctxt = 1000 ' Define topic
' context.
' Display message.
Response = MsgBox(Msg, Style, Title, Help, Ctxt)
If Response = vbYes Then ' User chose Yes.
MyString = "Yes" ' Perform some action.
Else ' User chose No.
MyString = "No" ' Perform some action.
Screen.PreviousControl.SetFocus
DoCmd.SetWarnings (False)
DoCmd.GoToControl "txtFirstName"
DoCmd.DoMenuItem acFormBar, acEditMenu, acSelectRecord, , acMenuVer70
DoCmd.DoMenuItem acFormBar, acEditMenu, acDelete, , acMenuVer70
DoCmd.GoToRecord , , acNewRec


End If


End If
ErrorHandlerExit:
Exit Sub
ErrorHandler:
If Err = 3021 Then ' no current record
Resume Next
Else
MsgBox "Error No: " & Err.Number & "; Description: " & Err.Description
Resume ErrorHandlerExit
End If

Does anyone know of a good way that if, for example, the search found multiple records that it would display the multiple records in a popup form. You could then select the record that you want in the popup and it would retrieve the record? It would be similar to a search function, I believe.
