Trouble with selective projectile script

Here is what I was hoping would happen. By default, the empty_object will shoot my crate rigid body when the mouse is clicked. BUT, if "2" is pressed at any time, than the object to be fired will be my earth object. And again if "1" is pressed the crate is reselected. Nothing visible is happening in-game, what did I mess up? And I do have object1 and object2 defined in unity, so thats not it.

 var object1 : Rigidbody;
 var object2 : Rigidbody;
 
 function Update () {
 var projectile : Rigidbody;
 var select = 1;
 if (Input.GetButtonDown("1") == true) {
     select = 1;}
 else if (Input.GetButtonDown("2") == true) {
     select = 2;}
     
 if (Input.GetButtonDown("Fire1") == true && select == 1) {
     projectile = Instantiate(object1, transform.position, transform.rotation);
     projectile.name = "Crate";
     projectile.velocity = transform.TransformDirection (Vector3.forward * 4000 * Time.deltaTime);}
 
 else if (Input.GetButtonDown("Fire1") == true && select == 2) {
     projectile = Instantiate(object2, transform.position, transform.rotation);
     projectile.name = "Earth";
     projectile.velocity = transform.TransformDirection (Vector3.forward * 4000 * Time.deltaTime);}
     
 }
