Need help with this problem:
"During an earlier in-lecture exercise, you developed a GUI interface like the one below. This assignment will involve modifying that application to include calculating the price of pizzas. Assume that the price of a small pizza is $10.95, the price of a medium pizza is $13.95, and the price of a large pizza is $16.95. The price of each topping (not including plain) is $1.00.
Modify the GUI so that it calculates and displays the total price for a pizza. You may choose how and where the price will be displayed. "
I have written code but I get errors so it won't compile. Can you help me correct the errors and explain why I did incorrectly?
