I'm taking a "self-paced" class trying to learn a little javascript. I'm doing the old Dino Quiz trying to add pop up alerts after a click on a radio button of any question. I only added the javascript functions "scoreQuestion" at the top. The rest was already typed for me to add the functions to. I've added everything that my book has in it exactly as it has it...or so I think. It says I should be receiving the pop up alerts but I'm not. Could someone please look over this and see what I missed. Thank you.
Jake
