Thanks for your reply. I've tested it out a little and have no problems running the study. Things get a little slow when I'm copying and pasting in the questionnaire - but the actual running (so far) seems to be okay.

I'm a little nervous about using access since I've never worked with it before. Would it be possible to create several questionnaire files (let's say 4) with the video files equally broken up among them and then participants randomnly get the videos from that questionnaire file. How would I set up the experiment to randomnly choose one of the four questionnaire files?

Thanks for your help!
