Hi Amy, when you are on the website you want, are you pressing ctrl + shift + i? That should open Dev Tools on Chrome. Sometimes if you have extensions that are getting in the way using "incognito mode" can help with that. I have to use incognito mode when debugging in JavaScript because of some Chrome extensions that prohibit it from working.
