lose health problem!

Hi, I have problem whit my health script…My player(FPS)dosn’t lose health…

My script is:

var health : float = 100;

function ApplyDamage( amount : float ){

health -= amount;

if ( health <= 0 ) Dead(); 

}

function Dead() {

print ( name + " is dead now.");

}

function OnCollisionEnter (theCollision : Collision) {
    if (theCollision.gameObject.tag=="Enemy"){
       ApplyDamage(10);
    }
}

Dont post double questions!
