Change Lives.loseLife(); to lives.loseLife();.

WARNING: Technical explanation below that you don't really need to worry about if you're just beginning.

Why? Lives (capitalized) refers to your Lives class. lives (lowercase) refers to an instance of your Lives class that's named lives.

When you call Lives.loseLife();, you're trying to call loseLife() from the class itself. Since it's public void loseLife() and not public static void loseLife(), it doesn't belong to the class itself. It belongs to instances of the class.

I hope that makes sense! Check out the Unity - Statics tutorial for more information.
