I am trying to make a programm where in one frame (window) I have a combobox, then after selecting the combobox value I want it to print a message based on it's value on another window (class), but it says 'int' object has no attribute 'comboBoxDiamUnitString'.

As you will see, I first create the main App, then open up the start page where the combobox is, I select it's value and after some other procees I didn't put in the code as it runs ok I get to the next window, but then I can't use the combobox value in this new class I am in...

What am I missing? Thanks for your help in advance.

class App(Tk):

    def __init__(self, *args, **kwargs):

        Tk.__init__(self, *args, **kwargs)



        MainMenu(self)

        #Setup Frame

        container = Frame(self)

        container.pack(side="top", fill="both", expand=True)

        container.grid_rowconfigure(0, weight=1)

        container.grid_columnconfigure(0, weight=1)



        self.frames = {}



        for F in (StartPage, PageOne, PageTwo):

            frame = F(container, self)

            self.frames[F] = frame

            frame.grid(row=0, column=0, sticky="nsew")



        self.show_frame(StartPage)



    def show_frame(self, context):

        frame = self.frames[context]

        frame.tkraise()



class StartPage(Frame):

    def __init__(self, parent, controller):

    Frame.__init__(self, parent)



    def confirmar():



        if (self.jobStep >= 0):



            respuesta = messagebox.askquestion( self.comboBoxDiamUnitString.get())



            if respuesta == "yes":

                respuestaInicio = messagebox.askquestion('Puesta en Marcha', 'Iniciar máquina')

                if respuestaInicio == "yes":

                    messagebox.showinfo("Inicio", "Iniciando máquina")

                    controller.show_frame(PageOne)



    self.comboBoxDiamUnitString = tkinter.StringVar()



    self.comboBoxDiametro = ttk.Combobox(self, state="readonly", width=5, values=["AWG", "mm"], justify="right", textvariable=self.comboBoxDiamUnitString)



class PageOne(Frame):



    def __init__(self, parent, controller):



    self.i = 10

    GPIO.setmode(GPIO.BOARD)

    GPIO.setup(13,GPIO.IN,pull_up_down=GPIO.PUD_UP)

    GPIO.add_event_detect(13, GPIO.FALLING, callback=self.interrupt, bouncetime=300)



def interrupt(self, controller):



        if(controller.comboBoxMetroVueltaString.get() == "Vueltas"):

            print("vueltas")

        if(controller.comboBoxMetroVueltaString.get() == "Metros"):

            print("metros")
