enter a trade-in value, use zero in your calculation. Validate the values

from the text boxes, displaying a message box if necessary.

To calculate, add the price of selected accessories and finish to the sales

price, calculate the sales tax and display the result in a subtotal label.

Then subtract any trade-in value from the total and display the result in

an Amount due label.

Include command buttons for Calculate, Clear & Exit. The Calculate

button must display the total amount due after trade-in.
