Hello, I cannot figure out why the program won't work beyond opening the MAIN window, can you please help to figure out the issue, I've provided all my code. The program is a Python Tkinter GUI Calendar and it's supposed to handle events. The MAIN window accepts the EVENT TITLE, and EVENT TIME. Then the program should open the SECOND WINDOW if the USER wants to ADD an event or the user has selected an event that already exists and they want to ALTER or VIEW it$.$
