Hey guys, I will try to explain my problem properly. I am using PsychoPy 3.2.4 - I first started building the experiment in the Builder and then configured the code in coding mode. I will have two participants doing the experiment, hence two monitors win0 and win1.
My problem is now: I want to analyze my data from the .csv file. It works fine, except for all values under the function [NAME].stopped: The program will save None. This applies to all saves .stopped values (other TextStimuli, etc). Thanks a lot! (This is just a code snippet of course, I hope its enough to identify the problem)
