I would like some help trying to prefill a yes/no question based on 3 other questions.
I've created a yes/no question and i've set the default value to "no" and i want it to change to "yes" if(agree== 1 && ( ! is_empty(birth) && ((time() - strtotime(birth)) / 60 / 60 / 24 / 365.25) > 18) && ( ! is_empty(live) && ((time() - strtotime(live)) / 60 / 60 / 24 / 30.436875) >= 6)
