tkinter button not accessing the command when clicked

[DT2000]

I have corrected your code so it will run but I am not sure what it is exactly that you are trying to do.

As I currently have it running the window opens with the "Click Me" button showing in the upper right corner "x=0,y=0", as you have it preset. When button1 is clicked the new button (button2), displays at "x=50, y=100" while button1 remains in the window.

When button2 is clicked the code then executes "resetCounter(counter)" which then assigns the value of "0" to the variable.

So as I see the code running it is performing what you are stating, or am I missing what you are trying to do here?

from tkinter import *

window = Tk()

counter = 0
def resetCounter(counter):
   counter = 0

def button1Clicked():
   global counter
   button2 = Button(window, text="click me when ready", command = resetCounter(counter))
   button2.place(x=50, y=100), + (counter*30)
   counter += 1

button1 = Button(window, text='Click Me', command = button1Clicked)
button1.place(x=0,y=0)

window.mainloop()
