The following code is for a simple server/client asplication that
allows the user to toggle between serve and or client modes and
send/recieve a message however i am getting an Attribute error on my
entry widgets when I try and call get() to get the port and ip address
from those fields, I'm sure it's something simple I haven't grasped...
