Why is it not colliding?

function create () {

 

game.physics.startSystem(Phaser.Physics.ARCADE);
enemy = game.add.sprite(103, 325, 'enemy', 'idle.png');
enemy.name = 'enemy';
game.physics.enable(enemy, Phaser.Physics.ARCADE);

enemy.scale.setTo(4, 4.3);// scale sprite image
enemy.anchor.setTo(0.5, 0.9);// move sprite image

 

}

 

function bulletHitEnemy (bullet) {

bullet.kill();
alert("Hello! I am an alert box!!");
}

 

function update () {

 

  game.physics.arcade.overlap(Bullet, enemy, bulletHitEnemy, null, this);

 

}

We're going to need more code. Where is Bullet being generated from?
