If it is correct it will add 1 to the persons score and go to the next question. If it is wrong it will just go to the next question. I am not sure how I will show the score.

Right now the best thing you can do is find examples, play with them, learn from them and make your own code. If you have any issues, let us know, but to get help, you must present a code with comments and put some effort into it.
