    Default code doesn't compile/run. It's supposed to show the total votes for both candidates, regardless of which button the user clicks on.

    Actually: It needs to Increment the number of votes by one when you click on the candidate's name, and show the total of both candidates.

    If it doesn't compile, it would be extremely helpful if you posted your compiler errors and indicate which line in your code causes these errors. Also, look at the forum FAQ to learn how to use code tags so we can more easily read your code.
