Hello, I am attempting to complete the Movie Finder exercise and I have gotten to the last step but it will not work. I tried to check the console to see what is wrong. it is telling me that It is creating an issue where on line 76 of the helpers.js (const randomIndex = Math.floor(Math.random() * movies.length)
says that .length is a type error as it is undefined. how do I fix this? the variable which gives the type error is movies.
