I don’t get any warnings when I edit that activity - are you still seeing the warning or have you fixed something in the meantime.
The dot instead of a tick means “nothing is incorrect on this page, but there’s something that cannot be marked automatically” - in your case, the table has no correct: sink so it doesn’t know how to mark this. Either make the table readOnly: true or add a correct: sink to it.
Thanks a lot,I had changed a variable name which cleared the warning but your suggestion to write readOnly:true on the table worked and put a tick on the dashboard, I didn’t know about that. I have been experimenting with having slides that mark both the table and the probability question and ones that just mark the question
