Hi,
I am trying to add image components for my stroop task experiment via excel. However, at first experiment runs but then closes when image trial comes.
I almost tried everything to make it work but nothing happens.
This is the error;
File “/Applications/PsychoPy.app/Contents/Resources/lib/python3.8/psychopy/tools/arraytools.py”, line 190, in val2array
raise ValueError(msg % (str(length), str(len(value))))
ValueError: Invalid parameter. Should be length 2 but got length 3.
################# Experiment ended with exit code 1 [pid:1016] #################
I am so sorry if I could not state my problem very clear but I’m very new at psychopy. Please help me! What am I doing wrong?
