How To Assign An Animation When Firing Weapon?

Hello All, I'm trying to adapt the FPS tutorial to a third person shooter and am having a problem: I've managed to equip the player with the machine and the bazooka by binding the Weapons game.object to it's hand and this works well - Pressing 1 brings up the machineGun and 2 the bazooka, and I can cycle through all the player's animations while holding the weapon - great. My problem is attaching my draw, aim, shoot, holster animations to the fire() function. The RocketLauncher js component looks like this:

var projectile : Rigidbody;
var initialSpeed = 20.0;
var reloadTime = 0.5;
var ammoCount = 20;
private var lastShot = -10.0;

function Fire () {

// Did the time exceed the reload time? if (Time.time > reloadTime + lastShot && ammoCount > 0) { // create a new projectile, use the same position and rotation as the Launcher. var instantiatedProjectile : Rigidbody = Instantiate (projectile, transform.position, transform.rotation);

 // Give it an initial forward velocity. The direction is along the z-axis of the missile launcher's transform.
 instantiatedProjectile.velocity = transform.TransformDirection(Vector3 (0, 0, initialSpeed));

 // Ignore collisions between the missile and the character controller
 Physics.IgnoreCollision(instantiatedProjectile.collider, transform.root.collider);

 lastShot = Time.time;
 ammoCount--;

}

}

When I add:

animation.CrossFade("draw_rifle");
 animation.Blend("aim_rifle");

within function Fire(), I receive an error message: "There is no 'Animation' attached to the "RocketLauncher" game object, but a script is trying to access it. You probably need to add a Animation to the game object "RocketLauncher". Or your script needs to check if the component is attached before using it."

Now, I dont think I want to add animations to the RocketLauncher component(or Weapons.object) as I want to keep each players animations contained and separate for multi-player.(besides, adding the animations to RocketLauncher did get the error to go away but the animations still wont play) So, how in js do I tell Unity that the animations are located within the player character? Or, am I adding the animation.Play code into the wrong component? Sorry to ramble, Thank you for your time.
