Form calculates amount to be paid

Hi,
this is about the locked thread https://www.chronoengine.com/forums/posts/f2/t88458/is-it-possible-to-chronoforms-to-add-values-from-fields.html
so I open a new topic.
After I added an Event switcher I notice that total field has to be clicked to show the good result
if not it displays the total value except the last amount edited
eg : if values are 2 / 3 / 1 / 4 / 6
total displays the value for 2 + 3 + 1 + 4 (10)
if user clicks on the field "total" it calculates finally 2 + 3 + 1 + 4 + 6 and displays 16
what could be the problem with the code please ?

window.addEvent('domready', function() {
$('total_soiree_restaurant').addEvent('change', rekenen1);
$('total_club').addEvent('change', rekenen1);
  $('total_coupe').addEvent('change', rekenen1);
   $('total_ski_seul').addEvent('change', rekenen1);
    $('total_buffet').addEvent('change', rekenen1);
     $('total_soiree_montagne').addEvent('change', rekenen1);
      $('total_ski_libre').addEvent('change', rekenen1);
});
function rekenen1(){
 $('total_a_payer').value = parseInt($('total_soiree_restaurant').value * 40)+ parseInt($('total_club').value * 15) + parseInt($('total_coupe').value * 30) + parseInt($('total_ski_seul').value * 22) + parseInt($('total_buffet').value * 25) + parseInt($('total_soiree_montagne').value * 60) + parseInt($('total_ski_libre').value * 22)}

Hi Repitol,

Try changing the code to use 'keyup' instead of 'change'.

Ok fine, I'll try
the website owner wants to apply a 4% majoration in case of Paypal payment
I think it has to be configurated in the Event switcher code
could you please tell me what to add ?

That's ok with keyup, thanks Bob you're the King !
for my 4% majoration, I will create a new "total" field called 'total_paypal"
and edit the Load JS Action to display the corresponding amount
then, my event switcher will be corrected to use 'total_paypal' when user chooses to pay with Paypal
I think that's the simpliest way according to my competencies.
