hello there make sure you have set a default value for cart in Store.js like this: https://github.com/bradtraversy/proshop_mern/blob/master/frontend/src/store.js#L69 also in the cartReducer you have a default value in the function parameter like this: https://github.com/bradtraversy/proshop_mern/blob/master/frontend/src/reducers/cartReducers.js#L10

you can clone this repo and run it on your computer. It works.

Then compare your code with this.
