Hello
you might want to take a look at the web app by wakecarter for counterbalancing and at his crib sheet for PsychoPy to PsychoJS auto-translation problems.
Notice that you should have JS-only or Both code-components instead of autotranslate code-components otherwise PsychoPy will always overwrite your manually entered JS-edits.
I have no idea why your exp.info box is so messed up. Probably, its size is fixed and your are exceeding its size. That’s why I would go for lists instead of “explaining” what to enter.
Best wishes Jens
