I was testing the questionnaire and every time I get to the 2nd RT task (with randomized $pos and $neg), there will be one item that shows "$pos.txt not found"....I have searched back and forth in my csv file and txt file, but all items look normal (at least all items look the same, and apparently only one stimuli shows the error message).
Would you help me with this issue? It is in the 2nd RT task, so you can skip the 1st task (it is long..).
Thank you so much!
