        });
    });
});

function newSum() {
    var sum=0;
    var thisRow = $(this).closest('tr');

    var total=0;

    //iterate through each input and add to sum
    $(thisRow).find("td:not(.total) input").each(function() {

    console.log($(this).attr('id') );
            sum += parseInt(this.value);                     
    }); 
    //change value of total
    $(thisRow).find(".total").html(sum);


     // the grand total
     $('.total').each(function() {
         total += parseInt($(this).html());
     });

    $('.result').val(total);
}


    </script>
