How to show next after a flash interactiv

Without the source files, the only option I can think of would be to keep the user on the page for XX number of seconds by not initially showing the next button. There would be no way to ensure they completed the interaction but you would force them to sit there for a certain amount of time before they could move forward in the course.Without the source files, the only option I can think of would be to keep the user on the page for XX number of seconds by not initially showing the next button.
