Beginning form problems

Hello all,

I am currently in my first semester of C# programming and just starting the form portion. Our assignment was to turn a rock, paper scissors console game developed earlier in the semester and turn it into a forms app. I have most of it operational, however, no matter the outcome, the draw label appears instead of the win or lose label. Not sure if it is an if, else if problem or what. Also I have been researching, but can not find anything to help me reset the game to play again. If you could look at my code and offer suggestions where to start or where i am going wrong it would be appreciated.
