**Tell us what’s happening:**

Hi!

I’ve been working on this challenge for a bit and after looking at the hints I understand that I was trying to do it in an unnecessarily complicated way, but I don’t understand why my current code doesn’t work. It succeeds with arrays that contain only numbers, but not with the ones that contain strings. For example, when I put in filteredArray([ [“trumpets”, 2], [“flutes”, 4], [“saxophones”, 2] ], 2), it logs flutes,4,.

Again, I now know that I should complete the challenge using .indexOf to make it simpler, but I’d just like to know what’s wrong with my current code.

Thanks!

**Your code so far**

```
function filteredArray(arr, elem) {
let newArr = [];
// change code below this line
for (let i = 0; i < arr.length; i++) {
let subArr = [];
let elemPresent = false;
for (let j = 0; j < arr.length; j++) {
if (arr[i][j] != elem) {
subArr.push(arr[i][j]);
} else {
elemPresent = true;
}
}
if (elemPresent != true) {
newArr.push(subArr);
}
}
// change code above this line
return newArr;
}
// change code here to test different cases:
console.log(filteredArray([ ["trumpets", 2], ["flutes", 4], ["saxophones", 2] ], 2));
```
