Form field not being updated

I have a web form where the user has a choice of selecting either Credit Card U.S. or Credit Card International.  The problem with the code is that the field "Convenience fee (2.3% for CC)" is not being updated with the correct amount when the user selects Credit Card - U.S. In other words, it still shows a "0". However it works with Credit Card - International where the correct amount is shown (please refer to attached screen shots). I am not sure what is causing the error. I have also attached the code. I would appreciate your help.

var fee_pct = 2.3;

      $('#fee')[0].value = Math.round(fee_pct*$('#subtotal')[0].value)/100.0;
    } else {
      $('#fee')[0].value = '0';
    }


change:

if ($('#pay_method')[0].selectedIndex == 0 || $('#pay_method')[0].selectedIndex == 1) {
      $('#fee')[0].value = Math.round(fee_pct*$('#subtotal')[0].value)/100.0;
    } else {
      $('#fee')[0].value = '0';
    }
    $('#total')[0].value = 1*$('#subtotal')[0].value + 1*$('#fee')[0].value;
  }

I made the change, but I am obtaining a syntax error  on the "if" statement.

I had to change it to this format for the error to go away

if (($('#pay_method')[0].selectedIndex == 0) || ($('#pay_method')[0].selectedIndex == 1)){

Is this the correct syntax?

please try this:
function update_total_add (idx, input_obj) {
  if (input_obj.value > 0) {
    $('#subtotal')[0].value = 1*$('#subtotal')[0].value + 1*input_obj.value;
    if (($('#pay_method')[0].val() == 2) || ($('#pay_method')[0].val() == 1) ) {
      $('#fee')[0].value = Math.round(fee_pct*$('#subtotal')[0].value)/100.0;
    } else {
      $('#fee')[0].value = '0';
    }
    $('#total')[0].value = 1*$('#subtotal')[0].value + 1*$('#fee')[0].value;
  }
}

or this:

function update_total_add (idx, input_obj) {
  if (input_obj.value > 0) {
    $('#subtotal')[0].value = 1*$('#subtotal')[0].value + 1*input_obj.value;
    if (($('#pay_method').val() == 2) || ($('#pay_method').val() == 1) ) {
      $('#fee')[0].value = Math.round(fee_pct*$('#subtotal')[0].value)/100.0;
    } else {
      $('#fee')[0].value = '0';
    }
