I recently found the form builder, and it\'s working exactly as needed. I run a football picks league, where we pick every game each week. I use a drop down for each game in my form to make those picks. I also have a bonus game that is based on the picks already made.

Is it possible to populate the last drop down with the previous 16 or so drop down choices?

Yes this can be done but it depends on your needs. I use mysql databases for my drop downs and add custom scripts. You could use the built in conditionals by generating lists and showing a certain list based on what was chose in the first. If you only have a few values and their not going to change then conditionals are the way to go. If your lists are going to change frequently then I would go the custom script direction.
