Piloting should let you run through the whole experiment a limited number of times, but it shouldn’t cut you off mid-experiment. At a glance, right now it looks like it just loops through list.xlsx once, and list.xlsx only has 12 entries, plus a start and of experiment, so I think you just need to update list.xlsx or increase the number of times it repeats. (Though repeating movies has proven to be tricky: Feedback video craches when trying to play for the second time)
The error with “could not find a record for experiment designer” is a new one on me, and out of my expertise. @apitiot do you know what that’s about?
