==================
Hi everyone !I am trying to randomly assign respondents to one of 4 scenario groups in my survey (LimeSurvey Cloud 6.17.1).My setup:

• I have a first group called "randomizer" containing a hidden Equation question with code 
  Code:

  rnd

   and equation 
  Code:

  rand(1,4)

• I have 4 groups, each representing one scenario
• Each scenario group has a relevance condition: 
  Code:

  rnd == 1

  , 
  Code:

  rnd == 2

  , 
  Code:

  rnd == 3

  , 
  Code:

  rnd == 4

The problem: None of the scenario groups ever display. When I preview the survey, I only see the "randomizer" group page (blank, as expected since the question is hidden), but after clicking Next, nothing appears — no scenario is shown.What I have tried:

• Code:

  rand(1,4)

   as the equation
• Code:

  if(is_empty(rnd.NAOK), rand(1,4), rnd.NAOK)

   as the equation
• Conditions: 
  Code:

  rnd == 1

  , 
  Code:

  rnd.NAOK == 1

  , 
  Code:

  {rnd} == 1

• When I remove the condition from a scenario group entirely, it displays correctly

The variable   seems to not be recognized in the group relevance condition (shown in red with "undefined variable").Any help would be greatly appreciated!Many thanks

Provide an LSS file that shows the issue. If you don't want to provide your whole study, you can copy it, delete everything that is not necessary, anonymize your questions and items and then export it as LSS and upload it here.

It can be minor things in the way you have set this up, so we need to see what you actually did. The description here can only help so much.
