Error message when trying to upload experiment to pavlova

Hello Maike

I used a similar approach to your condition-filename concatenation. It then started to fail on Pavlovia. I was too lazy to really dig into the problem. I simply switched to calling the filename from an Excel-sheet.

An alternative solution might be to store the value of "psychopy_list1/”+‘randcond’+“.xlsx” in a variable and call the variable instead of concatenating the filename. Keep in mind that you must store the value in the variable before you use it in the subsequent loop. I usually do this in a routine just before the loop.

e.g.

StimFileName = "psychopy_list1/”+ randcond +“.xlsx”

or

StimFileName =  "psychopy_list1B.xlsx”;
if ((Math.random() > 0.5)) {
    StimFileName =  "psychopy_list1A.xlsx”;
}

You might want to store the chosen StimFileName in your data file.

Best wishes Jens

Dear Jens, thank you very much for your response. I have now stored the value of "psychopy_list1/”+‘randcond’+“.xlsx” in a variable, like you suggested, and this has solved my problem. I am now able to upload my experiment to psychopy.
