bullet desent seem to apear (javascript)

hey, i messed arround with a bullet distroying code i had and ruined it I dont know why, it is supposed to:

• on a certain amount of time destroy it self.

• distroy it self when it colides.

.

 \#pragma strict
 
 var lifeTime = 100;    
 
 function Awake(){
     Destroy (gameObject, lifeTime*Time.deltaTime);
 }
 
 function OnCollisionEnter(collision : Collision){
     Destroy (gameObject);
 }

i tried moving its spawn point far from everything and it did not work either, so if some one could tell me what i did wrong, or could improve plz tell me.
