multi-choice parameters

[y-j-huang]

I'm trying to create a study with multi-choice questions but I have a hard time figuring out the parameters for it. It seems that either my practice_info or practice_trial or both doesn't work. I would appreciate it if someone could let me know what went wrong. Thank you!

var timeline = [];

var practice_info = [{questions: [{prompt: "I like vegetables", name: 'Vegetables', options: ["Yes", "No"], required: true}]},
{questions: [{prompt: "I like fruits", name: 'Fruits', options: ["Yes", "No"], required: true}]}
];

var practice_trial = {
    type: 'survey-multi-choice',
    questions: jsPsych.timelineVariable('questions'),
    prompt: jsPsych.timelineVariable('prompt'),
    options: jsPsych.timelineVariable('options'),
    required: jsPsych.timelineVariable('required'),
    data: {trial_part: practice}
};

var practice = {
    timeline: practice_trial
    timeline_variables: practice_info,
}

timeline.push(practice);

Hi @y-j-huang
if I understand the code correctly you might forget to add the [ ] in timeline practice_trial array.

var timeline = [];
var practice = {
    timeline: [practice_trial],
    timeline_variables: practice_info,
}
