Hi,
I do not see that the subquestions change the order.
I see that the questions are changed.
But this is obvious.
You know that the function "rand(x,y)" is triggered each time a click occurs on the page where there is this function.
The same behaviour as Excel.
Each click in the array triggers "randpsd" and the respective array is displayed.
Therefore we use this to generate a random number "{if(is_empty(randomnumber),rand(1,2),randomnumber)}"
So, either you revise your equation "randpsd" like
{if(condicao1 == condicao2,if(is_empty(randpsd),rand(1,2),randpsd),0)}
or you put the equation block into a separate group.
