Ref: Tutorial-> Beginners > 3. Scrollable Frames.

The code shows two classes:

class MyScrollableCheckboxFrame(customtkinter.CTkScrollableFrame):
    def __init__(self, master, title, values):
       ... 
    def get(self):
       ... 

and

class App(customtkinter.CTk):
    def __init__(self):
        ... 
        self.scrollable_checkbox_frame = MyScrollableCheckboxFrame(...)
        ... 
    def button_callback(self):
        print("checkbox_frame:", self.checkbox_frame.get())    
            # shouldn't this be print("scrollable_checkbox_frame:", self.scrollable_checkbox_frame.get()) ?   
        print("radiobutton_frame:", self.radiobutton_frame.get())  
            # why is this even here? we did not create any radio buttons in scrollalbe frame 

In the App class, the print block not refer to scrollable frame chebkoxes. It apepars to be a wrong copy/paste from earlier examples. How do I give this feedback to the Tutorial Instructors?
