Alternating between 4 stimuli list

[g-porta]

Hi! Apologies for bothering you.

I'm trying to design an acceptability judgement experiment. I have 4 lists of sentences, I want each participant to see one and only one of these lists. This means that participant 1 sees list 1, participant 2 list 2, and so on.
The lists have different stimuli (and the same filler items). Ideally, I don't want the sentences inside each list to be randomised, as I would like to present them in a specific order.

I have tried with alternate-groups, but it does not seem to be working. Here is my code:

var trial_structure = {
  type: jsPsychHtmlButtonResponse,
  prompt:
    "<p><em>Experiment prompt</em></p>",
   choices: ["1", "2", "3", "4", "5", "6", "7"],  
    stimulus: jsPsych.timelineVariable("sentence")
};

 var trial_1 = {
timeline: [trial_structure],
		  timeline_variables: [
      { sentence: "sentence 1, group 1" },
      { sentence: "sentence 2, group 1" },
      { sentence: "sentence 3, group 1" },
      { sentence: "sentence 1, group 2" },
      { sentence: "sentence 2, group 2" },
      { sentence: "sentence 3, group 2" },
            ],
            sample:{
                type: 'alternate-groups',
                groups:[[0,1,2],[3,4,5]],
                randomize_group_order: false
            }
		};

timeline.push(trial_1)

This only gets to show first group 1, and then group 2 (if randomize_group_order: true they get mixed), which is not what I want.

I tried to follow the code here, but again this doesn't do what I would like it to do.

One solution would be to have 4 different experiments, one per list, and be very careful with the participants, but I was wondering whether this process could be automatised!

Thank you in advance, and sorry for any mistake! It's my first time coding.
