Dear Philip,
Only the first two rows of your CSV file reference valid filenames for your Audio elements in the audio column. Most other rows simply have an extension-less word (eg. “cucumber” or “chocolate”) and some have an empty audio cell. Some rows have an extra (unnamed) column saying “both”. You should rework your CSV table and make sure it is properly formatted
When I run your experiment in the first group I can successfully run trial #1, although I need to add another wait command somewhere in the trial’s structure otherwise it only lasts ~750ms (the duration of the two Timer elements in the trial) which is not enough for me to interact with the elements on the page; once I do, however, I am able to play vegetables1.mp3
