          You may use jQuery for that purpose



          $("#mymodalrooms").on("change",function(){
          if($("#mymodalrooms").val()==="3"){
          $("#totalamount").val(parseInt($("#totalamount").val())+10);
          }
          });

            Add jquery to add value in amount. You can use on change event for this.



            $(document).on('change', '#mymodalnationality, #mymodalrooms, #mymodaladult, #mymodalchildren, #mymodalchildrenage', function(){
            var amount = $('#totalamount').val();
            amount = parseInt(amount) + 10;
            $('#totalamount').val(amount);
            });

                  You may use jQuery for that purpose



                  $("#mymodalrooms").on("change",function(){
                  if($("#mymodalrooms").val()==="3"){
                  $("#totalamount").val(parseInt($("#totalamount").val())+10);
                  }
                  });

                      Add jquery to add value in amount. You can use on change event for this.



                      $(document).on('change', '#mymodalnationality, #mymodalrooms, #mymodaladult, #mymodalchildren, #mymodalchildrenage', function(){
                      var amount = $('#totalamount').val();
                      amount = parseInt(amount) + 10;
                      $('#totalamount').val(amount);
                      });
