Here is what i want to do, check the image attached, javascript to sum the values of text boxes in a row having individual total, i have this but not working

  function sum() {
       var txtFirstNumberValue = document.getElementsByName('ca_score[]').value;
       var txtSecondNumberValue = document.getElementsByName('score[]').value;
       if (txtFirstNumberValue == "")
           txtFirstNumberValue = 0;
       if (txtSecondNumberValue == "")
           txtSecondNumberValue = 0;

           for(var i=0;i<txtFirstNumberValue.length;i++) {   

       var result = parseInt(txtFirstNumberValue[i]) + parseInt(txtSecondNumberValue[i]); }
       if (!isNaN(result)) {
           document.getElementsByName('total[]').value = result;
       }
   }
