Hello,

I am using your code in the help files to add few fields. That is working well. But I need it to add even when default values are assigned to the fields , so that the user sometimes need not need have to worry about typing a value.

This is the current code I am using.  

$(document).ready(function () {
   $('.sum').on('blur', 'input', sumtotal);
 function sumtotal() {
     var s = 0;
  $('.sum input').each(function () {
      s += parseNumber($(this).val());
  });
  $('.total input').val(s);
 }
 function parseNumber(n) {
     var f = parseFloat(n); //Convert to float number.
  return isNaN(f) ? 0 : f; //treat invalid input as 0;
 }
});
