function onChange(control, oldValue, newValue, isLoading) {

    if (isLoading || !newValue) {

        return;

    }

    var startDate = g_form.getValue('start_date');

    // 1️⃣ End date cannot be selected if Start Date is empty

    if (!startDate) {

        g_form.clearValue('end_date');

        getMessage('Please select Start Date first.', function(msg) {

        g_form.showFieldMsg('end_date', msg , 'error');

        });

        return;

    }

    // Convert string values to JS Date objects

    var start = new Date(startDate);

    var end = new Date(newValue);

    // 2️⃣ End date must be greater than Start date

    if (end < start) {

        g_form.clearValue('end_date');

        getMessage('End Date must be greater than Start Date.', function(msg) {

        g_form.showFieldMsg('end_date', msg , 'error');

        });
