Laura,

post me some code I have done a similar thing and got it working.....

let me see...

Oh yes I had to repack all the lower frames in order......

from Tkinter import *

root=Tk()


f1=Frame(root)
b=Button(f1, text='Close', command=root.quit)
b.pack()
f1.pack(side='top')

f1a=Frame(root)
l=Label(f1a, text='This should be in te middle')
l.pack()
f1a.pack(side='top')

def forget_f1():
    f1.pack_forget()
    
def remember_f1():
    f1a.pack_forget()
    f1.pack(side='top')
    f1a.pack(side='top')
    

f2=Frame(root)
b1=Button(f2, command=forget_f1, text='Forget')
b1.pack()
b2=Button(f2, command=remember_f1, text='Remember')
b2.pack()
f2.pack(side='bottom')
root.mainloop()

HTH
Martin.
