Unity v1.2.2 tutorial, page 17

I've created the 'Enemy script.js' as shown below and attached it to both of the enemies.

var score : Score;

function Update () {

if (transform.position.y < -2) {

Destroy (gameObject);
score.AddToScore ();
}
}

I've created the 'score.js' script as shown below and attached it to the GUIText object Score (which is actually a text object shown in the GameObject menu).

var score = 0;

function AddToScore () {

++score;
guiText.text = "Score: " + score.ToString ();
}

It keeps complaining about 'Assets/Working Assets/Scripts/enemy script.js(1) error BCE0018: The name 'Score' does not denote a valid type.' Stupid question, what am I missing?

 

got some help from the irc, the name of the script file wasn't uppercased. I need to follow Unities coding standard.
