There’s a problem with the code handling SendResults used as an in-trial command. Edit your file PennController.js and replace occurrences of e=window.items.indexOf(n); (there should be 2) with e=window.items&&window.items.indexOf(n);
Also, the audio replays if I type ‘r’ in my feedback comments—not sure how to prevent that as a general behavior, but it would involve a disable on the Key element that replays, or a printed test inside the Key element’s callback
