Gray Check (Dashboard)

Hi,

I made this activity with random numbers. I can’t seem to get the gray checkmark on the teacher dashboard for the first two screens. I thought what I wrote on the input was ok, but I guess not.

Type readOnly: true in the graph area.

Thanks a lot! I completely forgot about that.
