(sorry for top-posting). UpdateRecords and the other functions need to be
nested so they fall under your class. Right now they are functions, not methods.

Subject: How to get Buttons to work
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:
