There are two problems in this function, first you should _never_ use
two instances of Tk() in one program; if you need a second window, use
a Tkinter.Toplevel() instead.
Second, you assign var1 as textvariable for the Label; I think what you
actually intended is to set the current value of var1 as initial value
for var2 and then use var2 as textvariable for the label ? If yes,
simply change the first lines of newcount() into:
def newcount():
root2 = Tkt.Toplevel()
var2 = Tkt.IntVar()
var2.set(var1.get())
I hope this helps
Michael
