I am trying to create an experiment in which I present one of two versions of each video stimulus (e.g., Video 1 has versions A and B). I want E-Prime to randomly choose to present half of the videos as Version A and half of the videos as Version B, with no repetition (such that if Video 1A was shown, Video 1B will never be seen). How can this be done? (I'm very new to using E-Prime, so clear and simple instructions would be greatly appreciated!) Thanks.
