Problems with Randomization of Instructions

[lhunim95]

Hey there,

I am using jspsych for the first time and I am about to start an experiment on cognition.run next month. Therefore, I need to assign participants to four different conditions using a 2x2 design. There will be two different instructions (one for condition 1 and 2, and the second one for condition 3 and 4) and I tried to include this in my code, but there seems to be a mistake.
The assignment of participants to the four conditions works with the following coding:

var condition_assignment = jsPsych.randomization.sampleWithoutReplacement(['LIST1', 'LIST2', 'LIST3', 'LIST4'], 1)[0];

jsPsych.data.addProperties({
condition: condition_assignment
});

Afterwards, I created the two different instructions:

var instruction1 = {
type: 'instructions',
pages: ['

Here I used the first instruction

'],
show_clickable_nav: 'true',
button_label_previous: 'Zurück',
button_label_next: 'Weiter',
post_trial_gap: 1000
};
var instruction2 = {
type: 'instructions',
pages: ['

And here the second one

'],
show_clickable_nav: 'true',
button_label_previous: 'Zurück',
button_label_next: 'Weiter',
post_trial_gap: 1000
};
To finalize the randomization, I followed a solution that I found here on GitHub, but it does not work in my case:

var list_1 = [{stimulus: 'instruction1'}];
var list_2 = [{stimulus: 'instruction2'}];

var stimuli;
if (condition_assignment == "LIST1") {
stimuli = list_1;
} else if (condition_assignment == "LIST2") {
stimuli = list_1;
} else if (condition_assignment == "LIST3") {
stimuli = list_2;
} else if (condition_assignment == "LIST4") {
stimuli = list_2;
}

var instructions_rdk2 = {
type: 'html-keyboard-response',
stimulus: jsPsych.timelineVariable('stimulus')
};

var trial_procedure = {
timeline: [instructions_rdk2],
timeline_variables: stimuli
}

timeline.push(trial_procedure)

When assigning to List 1, there is just 'instruction1', so the variable name on the screen but not the instruction itself. For the other 3 lists, it does not work at all.

I might have done something stupid, this is my first time coding. So if someone has an idea or if you need further information, I would be very glad for an answer.

Thank you so much!

Update:
"When assigning to List 1, there is just 'instruction1', so the variable name on the screen but not the instruction itself. For the other 3 lists, it does not work at all."
-> this is now working :) so I just need help to show the actual instruction
