I am trying to add values from 6 text boxes and display its sum automatically in 7th text box. This is not working. Please help.


Code: Select all


function calculate_a() {
var a = document.getElementById('Para_A_A1_score').value ;
var b = document.getElementById('Para_A_A2_score').value ;
var c = document.getElementById('Para_A_A3_score').value ;
var d = document.getElementById('Para_A_A4_score').value ;
var e = document.getElementById('Para_A_A5_score').value ;
var f = document.getElementById('Para_A_A6_score').value ;
var g = (a+b+c+d+e+f) ;
document.audit_billing_IE.product_name4.value = g ;
}

<tr>
                    <td> Parameter A </td>

"Not working" doesn't mean anything ... Please, be more descriptive next time.


Try subtracting zero from each, thus converting to integer.

Code: Select all

var a = document.getElementById('Para_A_A1_score').value - 0;
var b = document.getElementById('Para_A_A2_score').value - 0;
