Hi Community!

i'm new to this forum, even though i've read a lot here within the last year.

I have a problem randomly selecting questions. I found some threads matching this but they are really old or not matching exectly my problem.

I have a questions group with 20 questions in it to be displayed. Each of this question has a different difficulty level and x questions to select from. Is there a way to get this working?

Example (difficulty level = df):
df1: Q1, Q2, Q3, Q4
df2: Q1, Q2
df3: Q1, Q2, Q3, Q4
df4: Q1
....
df20: Q1, Q2, Q3

The suvey group should look like this (example):
df1: Q3
df2: Q2
df3: Q4
df4: Q1
....
df20: Q2

This questions have to be the exact same if the user pause and continue the survey.

LimeSurvey Version 3.16.0+190225
No Customizations until now.

Thanks in advance!

Hi,
so you have 20 groups with different difficulty levels.
Each group contains 1 to four (or more) questions.
From each difficulty level you would like to select one question randomly.
Correct?

The easiest way:

First create 20 random numbers in questions of type equation. Like:
Question "Rand1": question text "{if(!is_empty(Rand1),Rand1,rand(1,[number_of_questions_in_df1]))}"
Question "Rand2": question text "{if(!is_empty(Rand2),Rand2,rand(1,[number_of_questions_in_df2]))}"

In each of your groups you select the displayed question by relevance equation
"df1Q1": relevance equation: Rand1==1
"df1Q2": relevance equation: Rand1==2
...
"df9Q3": relevance equation: Rand9=
...


Because of this {if(!is_empty(rr),rr,rand(1,x))} the random number is only calculated if it is empty. If not, it keeps its value.
