Hello, I need to make a multiplication of a div.class per a number (240). At the begging there's only one div.class but user can add new divs with the same class.

The problem is that the result of the multiplication does not change when the user adds or removes divs...

From what I can see, you never tell it to update the total. The total is only calculated in document.ready() which is called once when the page loads. You need to put the totalling in its own function, and call that functionfrom the add/delete function.

First, change this:

$(document).ready(function() {
       $(".total").text($("div.person").length*240);
});

to:

function update(){
   $(".total").text($("div.person").length*240);
}

then insert update() to:

C#

$(document).ready(function(){
   var counter = 2;

   update();

   $("#addButton").click(function (){
      // other code
      counter++;

      update();

   });

   $("#removeButton").click(function () {
      // other code
      counter--;
      $("#TextBoxDiv" + counter).remove();

      update();
   });

   // other code

});
