Hi Jorge,

You want to pull the value you sent through the intent into your fuelLevel variable.

You've declared the intent now you need to assign a value into fuelLevel(). For this, you call the getIntExtra method on the intent because you sent an integer through the intent.

The getIntExtra() method needs two parameters. First, the key of the key/value pair. This allows access to the the value which is what you're after. In this case, the key is "FUEL_LEVEL". The method also needs a fail value in case the key is wrong. The challenge wants a default of -1.

That all looks like: 

        // Add your code below!
        Intent intent = getIntent();
        fuelLevel = intent.getIntExtra("FUEL_LEVEL", -1);

I hope that helps.

Steve.
