I have just installed PsychoPy’s newest version on my computer, but I run into an error when using a conditions file to loop over trials. When calling upon the Excel file, I get this error message:
Attribute error: ‘OrderedDict’ object has no attribute ‘Stim1Pos’
(Where ‘Stim1Pos’ is the name of the first variable in my Excel conditions file.)
When running PsychoPy on an older version, I do not encounter this problem. Could you tell me what I should change?
