Mecanim controler problem

I had written a script with the intention to use an xbox controller (I'm using a 360 controller)

     public Image healthbar;
     public Text ratioHealthText;
 
     public Image staminabar;
     public Text ratioStaminaText;
 
     private float ratio;
 
     private const int maxStamina = 100;
     private const int maxHealth = 100;

     float walk;
     float punch;

     // Use this for initialization

     }
 
     public void Quit()
     {
         Application.Quit();
     }
 

for some reason I cant manage to get it to work with animations, does anybody else have this problem?
