I have a multiple choice question that is simply this:

Which of the following years did you participate (select all that apply)?
2019
2020
2021
2022
2023

A later question asks:

Relative to ${e://Field/largestYear}, how would you rate the following?

The embedded data value I want as “largestYear” is the highest selected year (most recent year) in the prior question.

This is the jscript attached to the first question:

Qualtrics.SurveyEngine.addOnload(function() {
    // Wait until the respondent has interacted with the question
    this.questionclick = function(event, element) {
        // Initialize max value
        var max = 2019;
        // Loop through selected choices
        jQuery("#"+this.questionId+" .ChoiceStructure tbody tr").each(function() {
            // Check if choice is selected
            if (jQuery(this).find(".Selected").length > 0) {
                // Retrieve numerical value of choice
                var value = parseFloat(jQuery(this).find("td:first").text());
                // Update max value if necessary
                if (value > max) {
                    max = value;
                }
            }
        });
        // Set the embedded data with the largest value
        Qualtrics.SurveyEngine.setEmbeddedData('largestYear', max);
    }
});

The resulting imbedded data in question two always turns out to be equal to the assignment in the jscript line var max = 2019 no matter what (numeric) value I put into that statement. This can’t be that hard. I’ve tried another approach like creating a function to call, but this produces no returned value:

Qualtrics.SurveyEngine.addOnload(function() {
    // Function to find the largest selected label
    function findLargestLabel() {
        var largestLabel = ""; // Initialize largest label variable
        var largestValue = -Infinity; // Initialize largest value variable

        // Loop through each choice
        this.questionChoices.forEach(function(choice) {
            // Check if choice is selected and its value is greater than current largest value
            if (choice.selected && parseFloat(choice.value) > largestValue) {
                largestValue = parseFloat(choice.value);
                largestLabel = choice.display;
            }
        });

        return largestLabel; // Return the largest label
    }

    // Set embedded data with the largest label when question is clicked
    this.questionclick = function(event, element) {
        var largestLabel = findLargestLabel(); // Call the function to find the largest label
        Qualtrics.SurveyEngine.setEmbeddedData('largestYear', largestLabel); // Set embedded data
    };
});

I can’t for the life of me figure out how to solve this seemingly simple problem, how to pipe the largest value of a multiple choice selection to the next question. Any assistance will be greatly appreciated. This question is also posted on Stack Overflow. Sorry for the cross posting.
