Hi ​@Saptatshi_das, 

Can you try the following code. Add the variables in the survey flow as “Lesser” “Greater” and “ParticipantResponse, include the code for the Slider question.

Qualtrics.SurveyEngine.addOnReady(function() {
    var participantResponse = parseInt("${e://Field/ParticipantResponse}"); // Get stored response

    if (!isNaN(participantResponse)) {
        var lowerBound = Math.max(participantResponse - 10, 0); // Adjust range as needed
        var upperBound = participantResponse + 10;

        var lesser = Math.floor(Math.random() * (participantResponse - lowerBound)) + lowerBound;
        var greater = Math.floor(Math.random() * (upperBound - participantResponse)) + participantResponse + 1;

        Qualtrics.SurveyEngine.setEmbeddedData("Lesser", lesser);
        Qualtrics.SurveyEngine.setEmbeddedData("Greater", greater);
        
        // Example of a mathematical operation
        Qualtrics.SurveyEngine.setEmbeddedData("ModifiedGreater", greater * 2);
    }
});


Thank you

Thank you ​@Nanditha MM for the reply. I have tried to execute the code but it is not working. I have created data fields so that JS can store the values. But it is not working. Am I doing something wrong ? I have used this code in the slider question so that It can store the response and compute. Should I change it to addonLoad or addonUnload?

// Generate numbers greater and lesser than participant's slider response
Qualtrics.SurveyEngine.addOnReady(function() {
    // Get the current question object
    var that = this;
    
    // Function to calculate values and update embedded data
    function calculateAndStore() {
        // For Qualtrics discrete slider questions, we need a different approach to get the value
        var participantResponse = null;
        
        // Try multiple methods to get the slider value
        // Method 1: Try to get the value directly from the question's input field
        try {
            var sliderEl = jQuery("#" + that.questionId + " .InputText");
            if (sliderEl.length > 0) {
                participantResponse = parseInt(sliderEl.val());
            }
        } catch (e) {
            console.error("Error getting slider value from input field: " + e);
        }
        
        // Method 2: If Method 1 fails, try getting from selected choices
        if (isNaN(participantResponse) || participantResponse === null) {
            try {
                // Get the selected choice index
                var selectedIndex = that.getSelectedChoices() 0];
                
                // Get the corresponding value from the choice list
                // Since your slider has specific values (0, 25, 50, ...)
                var values = h0, 25, 50, 75, 100, 125, 150, 175, 200, 225];
                if (selectedIndex >= 0 && selectedIndex < values.length) {
                    participantResponse = values/selectedIndex];
                }
            } catch (e) {
                console.error("Error getting value from choices: " + e);
            }
        }
        
        // Method 3: Last resort - try to read the displayed value
        if (isNaN(participantResponse) || participantResponse === null) {
            try {
                var displayedValue = jQuery("#" + that.questionId + " .track-label.active").text();
                participantResponse = parseInt(displayedValue);
            } catch (e) {
                console.error("Error getting displayed value: " + e);
            }
        }
        
        // Check if we have a valid number
        if (!isNaN(participantResponse) && participantResponse !== null) {
            // Define lower and upper bounds
            var lowerBound = 0;
            var upperBound = 225;
            
            // Log the captured participant response
            console.log("Captured Participant Response: " + participantResponse);
            
            // Generate a random number less than or equal to participant's response
            // This will be between lowerBound and participantResponse (inclusive)
            var lesser = Math.floor(Math.random() * (participantResponse - lowerBound + 1)) + lowerBound;
            
            // Generate a random number greater than or equal to participant's response
            // This will be between participantResponse and upperBound (inclusive)
            var greater = Math.floor(Math.random() * (upperBound - participantResponse + 1)) + participantResponse;
            
            // Store original response and generated values as embedded data
            Qualtrics.SurveyEngine.setEmbeddedData("ParticipantResponse", participantResponse);
            Qualtrics.SurveyEngine.setEmbeddedData("Lesser", lesser);
            Qualtrics.SurveyEngine.setEmbeddedData("Greater", greater);
            
            // Perform mathematical operation (multiply greater by 2)
            Qualtrics.SurveyEngine.setEmbeddedData("ModifiedGreater", greater * 2);
            
            // Log all generated values for debugging
            console.log("ParticipantResponse: " + participantResponse);
            console.log("Lesser Value: " + lesser);
            console.log("Greater Value: " + greater);
            console.log("Modified Greater Value: " + (greater * 2));
        } else {
            // Log error if participant response is not a valid number
            console.error("Invalid participant response value or no selection made");
        }
    }
    
    // Calculate initially when page loads (if a value is already selected)
    calculateAndStore();
    
    // Update calculation when slider changes
    this.questionclick = function(event, element) {
        calculateAndStore();
    }
    
    // Make final calculation when page is submitted
    Qualtrics.SurveyEngine.addOnPageSubmit(function() {
        calculateAndStore();
    });
});

This is the final code that worked for the above problem. I have the slider taking discrete values n0,225] in an increment of 25. The code is adjusted for that. Remember to create the Embedded data Fields “Lesser”, “Greater”, “ParticipantResponse” and “ModifiedGreater” before the block where the slider question is situated. And use these fields in the next blocks as you required.
