The trouble is in the `sendKeyDown()` function:

```javascript
function sendKeyDown(event) {
  var code = event.code;
  if (code == 'ArrowLeft') marker.position.x = marker.position.x - 5;
  isMovingLeft = true;
  if (code == 'ArrowRight') marker.position.x = marker.position.x + 5;
  isMovingRight = true;
  if (code == 'ArrowUp') marker.position.z = marker.position.z - 5;
  isMovingForward = true;
  if (code == 'ArrowDown') marker.position.z = marker.position.z + 5;
  isMovingBack = true;
}

```

As written, any time a key is pressed (any key – letters, numbers, arrows), this function will

- set `isMovingLeft` to `true`
- set `isMovingRight` to `true`
- set `isMovingForward` to `true`
- set `isMovingBack` to `true`

The `if` statements are only working on the line they are written on. That is, these two lines:

```javascript
  if (code == 'ArrowLeft') marker.position.x = marker.position.x - 5;
  isMovingLeft = true;

```

… say that _if the left arrow is pressed, then subtract 5 from the X position and ALWAYS set `isMovingLeft` to `true`._

What we want to say is _if the left arrow is pressed, then subtract 5 from the X position and if the left arrow is pressed, then set `isMovingLeft` to `true`._

In JavaScript, that is done with “curly braces”:

```javascript
  if (code == 'ArrowLeft') {
    marker.position.x = marker.position.x - 5;
    isMovingLeft = true;
  }

```

That says, _if the left arrow is pressed, then run the two lines of code inside the curly braces (subtract 5 from the X position and set `isMovingLeft` to `true`)._

After adding curly braces around all of the `if` statements in `sendKeyDown()`, that function will look like this:

```javascript
function sendKeyDown(event) {
  var code = event.code;
  if (code == 'ArrowLeft') {
    marker.position.x = marker.position.x - 5;
    isMovingLeft = true;
  }
  if (code == 'ArrowRight') {
    marker.position.x = marker.position.x + 5;
    isMovingRight = true;
  }
  if (code == 'ArrowUp') {
    marker.position.z = marker.position.z - 5;
    isMovingForward = true;
  }
  if (code == 'ArrowDown') {
    marker.position.z = marker.position.z + 5;
    isMovingBack = true;
  }
  
  if (code == 'KeyC') isCartwheeling = !isCartwheeling;
  if (code == 'KeyF') isFlipping = !isFlipping;
}

```

And then it will work as expected. EXCEPT for pressing the down arrow. There’s a bug in the `sendKeyUp()` function that’s preventing that from working. I’m betting you can find that problem, though, so I won’t tell. For now – ask if you can’t track it down 🙂

I found it, at the line 86 was KeyDown instead of ArrowDown.  
I finally found it, i spent like 1 Hour on it Debugging it.

Yay! Small mistakes like that are such a pain sometimes. I still do things like that all the time – and it sometimes takes me an hour to track down too!

But nice work tracking it down on your own – it’s good practice, and it eventually gets easier 🙂
