9,809 PointscalculateTaxes is a method for the Expense struct, that means that you can not call the method on its own. You need to have an instance of Expense and then call the method with the dot syntax. In this case, item is an instance of Expense and in order to call calculateTaxes you need to do it with your item like such: item.calculateTaxes(7.5/100). Note that your function will divide the argument percentage by 100, therefore there is no reason for you to do it in your method call. Hence the method call should be item.calculateTaxes(7.5)
