Help in finding ExceptionError

[menator01]

It's when I push the button to open a new top window.
I forgot to add the button for opening the window

    def my_footer(self, footerframe):
        '''footer'''
        style = ttk.Style()
        style.map('Footer.TLabel', \
        foreground=[('pressed', 'firebrick'), ('active', 'red')], \
        background=[('pressed', '!disabled', 'gray86'), ('active', 'gray86')] \
        )
        style.configure('Footer.TLabel', foreground='blue', \
        font=('Times', 12, 'normal', 'underline'))
        footer = ttk.Button(footerframe, text='Register for Johnny\'s CookBook', \
        style='Footer.TLabel', cursor='hand2', command=partial(opensite))
        footer.grid(column=0, row=0, ipady=3, padx=10, sticky='nw')


        form = ttk.Button(footerframe, text='Add Recipe', style='Footer.TLabel', cursor='hand2', \
        command=partial(AddRecipe().my_form))
        form.grid(column=1, row=0, padx=10)
