Hello,
the condition file for the loop is called stimulus.xlsx but the error message refers to a file stimulus list.xlsx. Any ideas why there is this discrepancies?
There is a folder called index.html. This should actually be a file and not a folder. So do you mind posting a screen shot of Experiment properties - Online?
What happens if you delete the folder index.html and resync. Is the folder index.html recreated or is there now a file called index.html?
Best wishes Jens
