### Tell us what’s happening:

let array = [1, 2, 3];  
array[3] = 10;  
console.log(array[rows]); // prints [1, 2, 10]  
Hello. Something is wrong with my code. Please, help me.

### Your code so far

```javascript
let character = 'Hello';
let count = 8;
let rows = ["Naomi", "Quincy", "CamperChan"];
console.log(rows[0]);

// User Editable Region

let array = [1, 2, 3];
array[3] = 10;
console.log(array[rows]); // prints [1, 2, 10]

// User Editable Region

```

Hi. You work on the code you already have, the rows array. Don’t use the example in your code.  
Note that zero based numbering is used for the index numbering , 0 is 1, 1 is 2.  
Reset the step and try again.
