I want to have a button for the player to click at the start of a new turn that will do some housekeeping, like add one field in a repeating section to another field and then zero out the first field. It would only do this depending upon the state of some checkboxes that are also fields in the the repeating section. The only way I can think of to do this is to have some control, like another checkbox, and hook up to its change event to do that housekeeping. Is there a way to hook up a function to a regular button? Or is there some better way than simply making the player click a checkbox?
