Set up an 'all of the above' answer option that automatically ticks the all answers

Hi Diana_A
Here's similar kind of question that might help you.

Thanks this worked partially. It can select all but I would want to select all apart from 'None' as I have that answer option as well. The none answer option is exclusive so it automatically deselects all and remains the only option clicked.
