How to get Buttons to work

[horgan.anton5 at gmail.com]

I am busy learning Python and I want to make a simple program that connects to a database to locate the information of Doctors. Now the as far as I can see everything works fine, database connects, info gets displayed, but the buttons don't want to work. Please see code and error below.

Any help will be greatly appreciated.

Error:

Traceback (most recent call last):
