2,759 PointsFirstly, Check the passengers spelling you have typed. It is "passengers" and not "passangers".
Secondly using the mSpaceship object you need to call the a method to get the passengers count which is getNumPassengers() method.
So access it as follows: mSpaceship .getNumPassengers() .
But this returns an int and setText method expects a String so mush it over as follows:
(mSpaceship .getNumPassengers() +"") (Adding an empty String makes addition operator work as an appender.)
So final solution is as follows:
mPassengersField.setText(mSpaceship .getNumPassengers() +"") ;

2,759 PointsYou need to set the text in TextView in LandingActivity using Spaceship class property getType() method as follows:
mTypeLabel.setText(mSpaceship.getType());
Hope this helps!
