==================
I created a script to apply to an array type question with 8 sub-questions. I entered it into the source in the HELP section of the question editor, but it does not work. As shown in the attached picture, the warning message appears the first time, but afterwards the 'submit' button does not work. I want the 'submit' button to function after displaying the warning message once, regardless of whether any changes are made. Thank you in advance.

<script type="text/javascript">
$(document).ready(function(){
    // Array of question codes
    var questions = ;

    // Intercept form submit event
    $('#limesurvey').submit(function(event){
        var sameAnswer = true;
        var firstAnswer = $('#javatbd' + questions[0] + ' .radio input:checked').val();
        
        // Check if the same answer is selected for all questions
        for(var i = 1; i < questions.length; i++) {
            var currentAnswer = $('#javatbd' + questions + ' .radio input:checked').val();
            if(currentAnswer !== firstAnswer) {
                sameAnswer = false;
                break;
            }
        }

        // If the same answer is selected for all questions, display a warning message
        if(sameAnswer) {
            // Check for previous warning message in local storage
            var warned = localStorage.getItem('warnedAboutSameAnswers');
            
            if (warned) {
                // If the warning message has already been seen, allow form submission
                return true;
            } else {
                // If seeing the warning message for the first time, display the warning message and stop form submission
                alert("You have selected the same answer for all questions. Please review your responses.");
                localStorage.setItem('warnedAboutSameAnswers', 'true');
                event.preventDefault(); // Stop form submission
            }
        }
    });
});
</script>

I don't have access to a computer today but it looks to me like the questions variable is undefined.

var questions = ;

I copied the questions variable above to the subject board, but it didn't show up. 

'Q3q1', 'Q3q2', 'Q3q3', 'Q3q4', 'Q3q5', 'Q3q6', 'Q3q7', 'Q3q8'

Hi,
so this is more or less just a warning - the respondent can proceed without any change.
Why not use a bootstrap alert.

And if you need a real confirmation : you can add a mandatory multi choice question with only one choice «I confirm I want to submit like this»

With the good condition to be show
 

Yes, there are multiple ways to do it. In fact, this is a method I use frequently, but using JavaScript and ExpressionScript has made the question heavier. Thank you.

I understand the flow of the ExpressionScript you suggested. Thank you. However, I'm not sure if I should put this in the help text editor source of the question editor, in the Relevance equation of the first sub-question, or in some other way. When I put it in the help text editor source, the entire script appears on the screen. I feel really embarrassed.

Edit:
@Denis was faster
 

Working solution


Condition here :
 

Thank you, @DenisChenu, @joffm. So, grouping two questions into one question group is also used in such situations.
