Corsi task, error messages

It’s about a Corsi task with Psychopy 1.84.2. This task uses an Excel file. After running the experience, an error message appears:

I don’t understand why they are problems. I have a windows computer.
Thanks for help

Hi @mamax, it looks like the issue is with setting the position of your blocks, perhaps there is an ' in your Excel cells. Would you mind sharing your conditions file?

Here is. Thanks
