 You should have a `selectedFortune` variable that is assigned a value based on the value of `randomNumber`.

 The `randomNumber` should correspond to its fortune. For example, if `randomNumber` is 1, the `selectedFortune` should be equal to `fortune1` and so on.
 
 ```js
-const condition1 = randomNumber === 1 && selectedFortune === fortune1;
-const condition2 = randomNumber === 2 && selectedFortune === fortune2;

 You should output the `selectedFortune` to the console.
