[Solved] Python Tkinter Frame interaction

Question

I am trying to have a form talk to another one as per exemple below.  I cannot find a way to make this work.  What am I doing wrong or missing
from tkinter import *
from tkinter import ttk
class FirstFrame():
def __init__(self,root):
self.root=root
self.frame=Frame(self.root)
self.PlaceLeftButton()
self.PlaceLabel()
def PlaceLeftButton(self):
self.btn=ttk.Button(self.root,text='Open Child Form',command=self.OpenChild)
self.btn.grid(column=0,row=0)
def PlaceLabel(self):
self.lbl=ttk.Label(self.root, text='At Start')
self.lbl.grid(column=1,row=0)
def OpenChild(self):
top=Toplevel(self.root)
self.child=ChildFrame(top)
class ChildFrame():
def __init__(self, root):
self.root=root
self.childframe=Frame(self.root)
self.PlaceLeftButton()
self.PlaceEntryField()
def PlaceLeftButton(self):
self.btn=Button(self.root,text='Reset parent form', command=self.SetParentValue)
self.btn.grid(column=0,row=0)
def PlaceEntryField(self):
self.entry=Entry(self.root)
self.entry.grid(column=0, row=1)
def SetParentValue(self):
self.root.lbl(text='Parent has been reset')
if __name__=='__main__':
root = Tk()
root.option_add('*font', ('verdana', 12, 'bold'))
root.title("Class Interaction")
display = FirstFrame(root)
root.mainloop()
I should add, it is the SetParentValue method I have no clue how to handle.
