The new feature of this application, compared to what you have done in previous iLabs, is that the values entered by the user will be checked for validity. If the amounts entered are invalid, the application will display appropriate error messages to the user. If the input data are valid, the application will calculate the sales tax due and the total, including tax. Sales Tax Application Business Requirements The user enters an order amount and a sales tax percent. The order amount must be numeric and greater than 0. The sales tax percent must be numeric, greater than or equal to 0, and less than or equal to 0.14. If the input data are invalid, appropriate error messages will be displayed to the user. If the input data are valid, the application will calculate the sales tax by multiplying the order amount by the sales tax percent, and will calculate the order total, including tax, by adding the order amount and the sales tax. The sales tax and the order total, including tax, will be displayed to the user.
