We want to run a movie. If the participant has an answer
he can push a button to stop the film and then write down
the answer (till here it’s no problem).
but now, if the solution is not correct, we want the film to
go on. So that the same procedure will be repeated but
the participant can try to answer again without
see the hole movie from the beginning on.
Is it possible to do this? And if yes, how?
Thanks for your help!
