That partially worked. I received very strange results of computation:
I have equation question
EQ1= {if(is_empty(Q1.naok), 1, 0)+if(is_empty(Q2.naok), 1, 0)+if(is_empty(Q3.naok), 1, 0)}
and three questions with relevance conditions:
Q1: EQ1=
Q2: EQ1==2
Q3: EQ1<2
I need to show next of Q1-Q3 each time token enters the survey.
Now is works 1st and 2nd times, but after that EQ1 fixes on value 2 and never changes again. I have a suspicion that after second entry with same token equation questions just stop any calculations. But how to fix it haven't got a clue.
