Camera animations transition smoothly?

I want my main camera to do the "Camera_WhileRunning" animation while running (pressing left shift). I also created an idle animation for the camera so I could use the animation.CrossFade but the script is not working at all. The camera can only be moved along Y and the animation is not fading over to the other one. Can someone help me out?

The camera animations are playing on a gameobject which is a child of the Player and the parent of the Main camera.

 var animObject : GameObject;
 var running : boolean = false;
 

 function Start() {
     running = false;
 }
 
 
 function Update() {
     if(running == false) {
         animObject.animation.CrossFade("Camera_Idle");
     }
 
     if(Input.GetKeyDown("left shift")) {
         running = true;
         animObject.animation.CrossFade("Camera_WhileRunning");
     } else {
         running = false;
     }
 }
