NameError: name 'value1' is not defined

I was New to Programming and Python and I was trying Tkinter then I run on this Problem, It will always run on an error when it got to the last click for the Button.
I want to get all the Value from value1-5 but it always say "NameError: name ‘value1’ is not defined".
I try defining value1-5 from inside to outside the function and class but it turn to 0 or " "

Please Help

        Print2.grid(row= 4)

>Solution :

Did you mean to use an instance of Spam?

class Spam:

    def click1(self):
        
        self.value1= (s1.get())
        Text1 = Label(window, text = self.value1)
        Text1.grid(row= 3)
        Print2 = Label(window, text = "2nd Number:")
        Print2.grid(row= 4)
        
        b1.configure( text= 'Submit',command= self.click2)
        s1.delete(0, END)

    def click2(self):
        ...

    def SumAll(self):
      
        s1.delete(0, END)      
        b1.destroy()
        Sum= self.value1 + self.value2

# ...

s = Spam()
...
b1 = Button(window, text = 'Submit', command = s.click1)
