    Hi @RAVI,

    I think you could implement something like the following, which is a bit simpler.

    footerCallback: function (row, data, start, end, display) {
     var api = this.api();
     // Calculate sum for the third column (index 2)
     var column3Data = api.column(2, { page: 'current' }).data().reduce(function (a, b) {
         return parseFloat(a) + parseFloat(b);
     }, 0);
     total = api.column(2).data().reduce(function (a, b) { return parseFloat(a) + parseFloat(b); }, 0);
     // Total over this page
     // Update footer
     $(api.column(2).footer()).html(column3Data.toFixed(0) + '(' + total.toFixed(0) + ')');
     // Assuming 2 decimal places
 },
