Having trouble on the tutorial

ok...im working on the ghost shooter tutorial and trying to add events when i go to add Mouse.X and Mouse.Y to the set angle towards it tells me Mouse.X is not an object name????? I've done everything the tutorial told me can anyone tell me whats going on?>>

Did you add the Mouse object? From page 2:

b]Add the input objects

Turn your attention back to the layout. Double click to insert another new object. This time, select the Mouse object, since we'll need mouse input. Do the same again for the Keyboard object.

(Edit: moved to Construct 2 'how do I?' forum.)
