Javascript code to set validation using the previous selected options and current rank oder

Hi all,

I am new to javascript. The validation rule I want is that respondents pass current Rank Order if the options ranked in the last two positions of the current Rank Order question are the same as the options selected in the previous Multiple Choice question (both questions have identical options and corresponding recode values). If this condition is not met, the respondent should see a warning (like a forced response message in red text below the question) when they click next. How can this be implemented in JavaScript and html view? Below is the code Qualtrics Support AI Assistant gave me (and I replace QID with ones in my project) but did not work. I greatly appreciate for any help!

Html view is

<p>Please rank the following options:</p>
<div id="warningMessage" style="color: red; display: none;">Please ensure the last two ranked options match the selected options in the previous question.</div>

Javascript is below (no function in addonload and addOnUnload)

Qualtrics.SurveyEngine.addOnReady(function() {
    // Get the question IDs
    var mcQuestionId = "QID1"; // Replace with the actual ID of the Multiple Choice question
    var roQuestionId = "QID2"; // Replace with the actual ID of the Rank Order question

    // Get the warning message element
    var warningMessage = document.getElementById("warningMessage");

    // Function to check the condition
    function checkCondition() {
        var mcSelectedValues = [];
        var roRankedValues = [];

        // Get selected recode values from the Multiple Choice question
        jQuery("#" + mcQuestionId + " .q-checked").each(function() {
            mcSelectedValues.push(jQuery(this).find("input").val());
        });

        // Get ranked recode values from the Rank Order question
        jQuery("#" + roQuestionId + " .ranked").each(function() {
            roRankedValues.push(jQuery(this).find("input").val());
        });

        // Check if the last two ranked values match the selected values
        var lastTwoRankedValues = roRankedValues.slice(-2);
        var conditionMet = mcSelectedValues.every(value => lastTwoRankedValues.includes(value));

        // Show or hide the warning message
        if (!conditionMet) {
            warningMessage.style.display = "block";
        } else {
            warningMessage.style.display = "none";
        }

        return conditionMet;
    }

    // Add event listener to the Next button
    jQuery("#NextButton").click(function(event) {
        if (!checkCondition()) {
            event.preventDefault(); // Prevent the form from submitting
        }
    });

    // Add event listener to the Rank Order question
    jQuery("#" + roQuestionId + " .ranked").on("change", function() {
        checkCondition();
    });
});
