Hi Mike, I was responding to the original questioner and letting them know of a solution I found, rather than indicating any particular need I have. However, thanks for the tip about changing the country names rather than coming up with new ones--I was thinking about adding new countries without removing any of the already existing countries.

KC -  I am not sure I am understanding what you are needing.  You can already, as you describe above add any country you want that we don't already have.  You can even update existing countries with new names.  So, for example you could take the country that has SC and change the name to Scotland  Can you clarify your need?  Thanks..

Hi Dougie--I think I just recently found out this is available! You go to Management--System Defined Fields--Country Codes, and then if you show the Disabled fields every country is there. Scotland is not available, but I added it with a new letter code (I had to give it a weird letter code, LD, since the obvious choices like SL and SD are already being used for other countries). I refreshed all of my forms by "replacing" the current one with a new one, and the new country, Scotland, had appeared in the dropdown. I think you should be able to do this for all of the countries you want to add.
