I am new to PsychoPy and I am attempting to create an experiment where the number of trials varies over the course of a loop. Each loop calls a new spreadsheet which contains all of the trials that need to be run. During the first run, I have 8 trials, then 16, and 24. In the next loop, I have only 16 trials included in the spreadsheet but when I run the experiment, those 16 trials will be shown, then PsychoPy presents blank slides for the additional 8 trials. Why would PsychoPy attempt to run items that don’t exist in the spreadsheet?
I appreciate any help!
