Android Build an Interactive Story App (Retired) Intents and Multiple Activities Putting Data in an Intent

I am having the problem with this challenge.

We've updated our LaunchActivity to include a fuel level (mFuelLevel) for the spacecraft. This value needs to be passed to the FlightActivity. Add the code to pass this value along via the Intent. Use the key "FUEL_LEVEL".

import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;

public class LaunchActivity extends Activity {

  public Button mLaunchButton;
  public int mFuelLevel;

  protected void onCreate(Bundle savedInstanceState) {

    // mFuelLevel is set elsewhere.
    // Code ommitted for brevity!

    mLaunchButton = (Button)findViewById(R.id.launchButton);
    mLaunchButton.setOnClickListener(new View.OnClickListener() {
      public void onClick(View v) {
        // Add your code in here!
        Intent intent = new Intent(LaunchActivity.this, FlightActivity.class);
        intent.putExtra(" mFuelLevel", mFuelLevel);

The instruction says to use "FUEL_LEVEL" as the key:

intent.putExtra("FUEL_LEVEL", mFuelLevel);

This is how it should look:

 intent.putExtra("FUEL_LEVEL", fuelLevel);

Don't forget Java is case sensitive.
