BuddyPress.org

Hi! I’ve been searching without success.
I am importing information from a form to the buddypress profile.
But a field is an array (cities of the world that you chose) and when i trying to add it as checkbox it is not possible if it has not been loaded before, is there any way to do it?

For example as it is imported in text line:
Paris, Francia, Buenos Aires, Argentina (these are google places)
like i need in check box

Paris, Francia
Buenos Aires, Argentina

thanks!!
