Hi, there is always this confusing about the word "randomization".
It is user for
- I want to show all groups but in randomized order
Buzzword "Randomization group name"
- I want to show one out of x groups randomly selected.
Buzzword "random number"
So to select one of the four groups you should create a random number (rn)
{if(is_empty(rn),rand(1,4),rn)}
and set the condition of
Task1 : rn==1
Task2 : rn==2
...
And I assume the questions inside the groups you want to show in randomized order.
Here you set the "randomization group name" of the questions involved to the same name.
If I misunderstood, please explain again.
