I can confirm that the solution by Rolf works. There seems to be one little bug though. If you actually drop down the city list and select the name of the city, it will automatically populate the Country field.
If you start typing in the name of the city and the correct one shows up, then press tab to go on to the next field the country field will not populate. I know in the javascript world that’s a difference between an onclick event and an onchange.
Anyways just thought I’d report my findings. Thanks again for the tip. I think at the moment it should work well for us especially since we would mark many clips at a time for one city.
