Spawner Doesn't Spawn at the Right position

I am making a spawner and I want it to spawn at the position I want!

Script:

var projectile : GameObject;
var position : Vector3;

InvokeRepeating("LaunchProjectile", 0, 10);

function LaunchProjectile () {
var instance : GameObject = Instantiate(projectile,position);
}

This won’t even compile. There is no two parameter version of Instantiate(). Change line 6 to:

 var instance : GameObject = Instantiate(projectile,position,Quaternion.identity);
