Conditional timeline base on several choices

[Nega100]

I use multiple select plugins to develop conditional timeline with several (three) choices. If these choices (A, B, C) were selected the condition will be 1, and if three choices + one or more choice added will be condition 2 (A,B,C,D).

var Q1 = ["A", "B", "C", "X", "Y", "Z"];

var multi_select_block = {
    type: 'survey-multi-select',
    questions: [
      {prompt: "Task1", name: 'Ques1', options: Q1, required:true}
    ],
    data: {segmen: 'Teach'}
  };
  timeline.push(multi_select_block);
 
var cantVaccinefeedback = {
      type: 'html-keyboard-response',
      stimulus: '<p><b>Condition_2</b></p>',
      choices: jsPsych.NO_KEYS,
      trial_duration: 10000,
      on_finish: function(){
        jsPsych.endExperiment()
      }
    };

var cantVaccineDM = {
        timeline: [cantVaccinefeedback],
        conditional_function: function() {
            var stayHomeDM = JSON.parse(jsPsych.data.get().last(1).select('responses').values);
            var ariseDM = Object.values(stayHomeDM)
            console.log(ariseDM)
           if (ariseDM[0] == 'A') {
                return false
            } else if (ariseDM[1] == 'B') {
                return false
            } else if (ariseDM[2] == 'C') {
              return false
            } else if (ariseDM[3] == 'D') {
              return true
            } else if (ariseDM[4] == 'D') {
              return true
            } else if (ariseDM[5] == 'E') {
              return true
            } else if (ariseDM[6] == 'F') {
              return true
            }
        }
  };
  timeline.push(cantVaccineDM);

var yesVaccinefeedback = {
      type: 'html-keyboard-response',
      stimulus: '<p><b>Condition_1</b></p>',
      choices: jsPsych.NO_KEYS,
      trial_duration: 5000,
      on_finish: function(){
        jsPsych.endExperiment()
      }
    }
    timeline.push(yesVaccinefeedback)

I know that conditional timeline will executed first trial in timeline as Josh mentioned, if that the case, is there any other solution. Thanks alot!!

Hi @Nega100,

I'm not quite sure what the question is here. Is this not working as you want?

Something like this Josh

var stayHomeDM = JSON.parse(jsPsych.data.get().last(1).select('responses').values);
            var ariseDM = Object.values(stayHomeDM) 
            console.log(ariseDM)
            if (ariseDM[0] == "Yes" && (ariseDM[1] == 'Yes' || ariseDM[2] == 'Yes')) {
              return false //condition A
            } 
            if (ariseDM[0] == "Yes" && (ariseDM[1] == 'Yes' || ariseDM[2] == 'Yes' || ariseDM[3] == 'Yes')) {
              return true // condition B
            } 

However the result always in condition A.
