I'm sure I'll kick myself tomorrow for asking this today.
I have a need for a very simple value list: two items, the current year and the previous year. (As of last week, the items need to be 2015 and 2016; come next January, they must be 2016 and 2017.) Filemaker gives lots of tools to create a list, but few that let me use it for a radio button set -- no way to script the creation of a named value list. A virtual list seems like overkill. It would be simple enough to hard-code and change once a year, and that's beginning to look like the best answer. Perhaps someone here can help me set my sights on that one tree --- all I see right now is the forest.
