I can not get the radio buttons to give me an alert in an if statement to connect with my score box

I am trying to make it so when a user clicks yes then the game will track the users matches and moves. if the user clicks no then it won't. but I cant even get an alert to appear when the user clicks the yes radio button and I don't know why. I have been looking all over for answers but nothing I have done seems to work. I need this to be all javascript and no jQuery.... also no vanilla or anything else like that. if anyone needs any more details let me know.
