We'll modify the code to display the `x` acceleration if the `A` button is pressed. For that, we need to store `acceleration (x)` in a new variable `ax` and use a `button (A) is pressed` to detect if the button is pressed.
```blocks
basic.forever(() => {
let az = input.acceleration(Dimension.Z)
let ax = input.acceleration(Dimension.X)
if (input.buttonIsPressed(Button.A)) {
basic.showNumber(ax)
}
basic.showNumber(az)
})
```
* Run the code to see if it works as expected.
### Challenge 2
Display the `y` acceleration when `B` is pressed by adding another `if` statement using `button (B) is pressed`.
