Your app should satisfy the following requirements: 1. Define the Click event for a Button to calculate and display the value of the Total Due (Total Amount * Tax Percentage). Check if all the controls carry values (for example if nothing is entered, display a warning message) 2. Note that Text property is of string type and require conversion before arithmetic is performed. 3. The font color for all objects should be of your choice. Change the background color of the objects also to an appropriate one to use with your font color. To change the background color of the form you can use configure method (For example, window.configure (bg="blue'))
