              if ( $(ele).attr("name") === "priceMonthly" ) {
                  if (!$.isNumeric($(ele).val())) {
                      return ($(ele).val()*30); //not working
                  }
              }
  
            var newText = event.target.value ;
              $(ele_place).html(newText); 
          });
      }
  
  
      keyup_fill("#priceMonthly", "#priceMonthly-place");
