Code:
echo "hidden";

6.Insert the static text (<span> element) on the page. 
7.Define an id for it: "total_span". 
8.Define IDs for your text boxes (e.g. "textbox1", "textbox2", "textbox3"). 
9.Add this JS-code in "onchange" event of every text box: 

Code:
calculate();

10.Open JS ditor and add at the end the following: 

Code:
function calculate(){ 
 var value1 = document.getElementById('textbox1').value; 
 var value2 = document.getElementById('textbox2').value; 
 var value3 = document.getElementById('textbox3').value; 
 if (value1 == '') value1 = '0'; 
 if (value2 == '') value2 = '0'; 
 if (value3 == '') value3 = '0'; 
 var total = parseInt(value1) +parseInt(value2) +parseInt(value3); 
 document.getElementById('total_span').innerHTML=''+total; 
 document.getElementById('total').value=''+total; 
}


After that you will have a capability to insert a value of "total" in your email template through the simple dynamic variable.
