Have you found a solution? I’m facing the same issue!
I tried adding the code (while leaving the previous one) but nothing happens…am I doing something wrong?
Thank you very much!
This is much appreciated! Your solution works perfectly as long as you select maximum 3 boxes, but you can still select just one or two.
Is there a way to make it work as exact number? So the user must select exaclty trhee options, no more and no less?
Thanks again!
