C# GUI code help

I have the same GUI Form to create as someone else on this forum had. I have tried their code and added some more to it but still have no luck making it work. I am pasting the assignment instructions and the code they have along with my additional added code. I need some kind of guidance please.

 

Create a Form that contains two randomly generated arrays, each containing 100 numbers. Include two buttons labeled initially 1 and 2. Starting with position 0 in each array, ask the user to guess which of the two arrays contains the higher number and to click one of the two buttons to indicate the guess. After each button click, the program displays the values of the two compared numbers, as well as running counts of the number of correct and incorrect guesses. After making a guess, disable the buttons while the user views the results. Require the user to click a 'Next' button the user can make another guess using the next two array values. If the user makes more than 100 guesses, the program should reset the array subscript to zero, so that the comparison can start over. But continue to keep a running score.
