Find total sum of 2 columns

I have a table that has 2 columns that auto sum to "Monthly Subtotal". I need to add both of these subtotals together to display in the "Monthly Total" field. I have little to no knowledge of JS, can someone please help.

here it is

function startCalc(){
  interval = setInterval("calc()",1);
function calc(){
  one = document.autoSumForm.firstBox.value;
  two = document.autoSumForm.secondBox.value; 
  document.autoSumForm.thirdBox.value = (one * 1) + (two * 1);
function stopCalc(){
<div style="width: 200px; text-align: center;">
<form name="autoSumForm">
<input class="right" type=text name="firstBox" value="" onFocus="startCalc();" onBlur="stopCalc();"><br>
+ <input class="right" type=text name="secondBox" value="" onFocus="startCalc();" onBlur="stopCalc();"><br>
= <input class="right" type=text name="thirdBox">
