Total price and Quantity in Javascripts

Hi guys am trying to get the Total price and quantity of each items. So, i have a fixed price of $20. the price comes out fine but its not counting the quantity of each items

This is the code for Total Quantity and this works fine in an input field.

function changeval1() {
    $total = parseInt($("#A1").val()) + parseInt($("#B1").val()) + parseInt($("#C1").val()) + parseInt($("#D1").val()) + parseInt($("#E1").val());

    $('.A').val($("#A1").val());
    $('.B').val($("#B1").val());
    $('.C').val($("#C1").val());
    $('.D').val($("#D1").val());
    $('.E').val($("#E1").val());
    $('.total').val($total);
}

HERE IS THE PROBLEM when i add this code, the Price comes out good but the quantity no longer SHOWS.

function changeval1() {
    $price = parseInt($("#A1").val() * 20) + parseInt($("#B1").val() * 20) + parseInt($("#C1").val() * 20) + parseInt($("#D1").val()* 20) + parseInt($("#E1").val()* 20);

    $('.A').val($("#A1").val());
    $('.B').val($("#B1").val());
    $('.C').val($("#C1").val());
    $('.D').val($("#D1").val());
    $('.E').val($("#E1").val());
    $('.price').val($price);
}

so i want to have something like this

PRICE = 20 QUANTITY= 1 PRICE = 40 QUANTITY= 2 '' '' since i have 20 as a fixed price. Any help will be appreciated.
