Gordon,
The document you attached didn't have code looking anything like that. If you are simply replacing an English value with a French value use:
Code:
Private Sub Document_ContentControlOnExit(ByVal CC As ContentControl, Cancel As Boolean)
Dim lngIndex As Long
With CC
Select Case .Title
Case "condition"
For lngIndex = 1 To .DropdownListEntries.Count
If .DropdownListEntries(lngIndex).Text = .Range.Text Then
ActiveDocument.SelectContentControlsByTitle("conditionFR").Item(1).Range.Text = .DropdownListEntries(lngIndex).Value
Exit For
End If
Next lngIndex
'Case and so on.
End Select
End With
End Sub
