I can't edit my animation or play my other animation

I have done everything possible for this, however, for some reason I can't edit my animation or even open it for that matter in the Unity engine. Could it be because I edit the name on the animation? Also, while were at it for some reason I cannot use my Sword Mechanic that I was able to use before. To help trouble shoot the problem I'll show vids, and pics so I can show you what the problem here is.

My Code for the character:

 //if statements should be highly recommended to use when a statement out of an if statement is preformed. 
 
 var Character : Rigidbody;
 var CharacterHealth : int = 100;
 var timer : int = 0;
 var JumpLimit : int = 2;
 var NumberofSwings : int = 0;
 var TimesSwungSword : int = 3;
 var OnlyOneTime : int = 1;
 var NumberofJumps : int = 0;
 var CanYouJump : boolean = false;
 var cam : Quaternion;
 var WalkingAnimation : Animation;
 var SwingingSword : Animation;
 var Blocking : Animation;
 var SwordMegaSlash : Animation;
 var CharacterSound : AudioSource;
 var CharacterAttack : AudioSource;
 var CharacterBlock : AudioSource;
 var CharacterBlockSoundEffect : AudioSource;
 
 function Start() 
 {
     cam = transform.rotation;
 }
 
 function Update()
 {
     //The Control Panel for All the Mechanics down Below
     var Walk = Vector3(10, 0, 0);
     var JumpHeight = Vector3(0,20,0);
     var WalkLeft = Vector3(-10, 0, 0);  
     var JumpMechanic = Input.GetKeyDown("space");    
     var WalkRightMechanic = Input.GetKey("d");
     var WalkLeftMechanic = Input.GetKey("a");
     var SwordMechanic = Input.GetKeyDown("e");
     var BlockMechanic = Input.GetKeyDown("b");
     NumberofJumps = JumpLimit;
     NumberofSwings = TimesSwungSword;
 
 
     
     //Where the action is taken place                         
     if(WalkRightMechanic)
     {
         Character.velocity = Walk; 
         WalkingAnimation.Play(); 
     }
             if(WalkLeftMechanic)
             {
                 Character.velocity = WalkLeft;
                 WalkingAnimation.Play(); 
             }
                     if(JumpMechanic&&CanYouJump == false&&NumberofJumps == JumpLimit)      
                     {
                         CanYouJump = true;
                         Character.velocity = JumpHeight;
                         CharacterSound.Play();                            
                     }
                         if(SwordMechanic) 
                         {
                             SwingingSword.CrossFade("SwingingSword");
                             CharacterAttack.Play();                
                         }
                         if(SwordMechanic&&NumberofSwings == TimesSwungSword)
                         {
                             SuperMegaSword.CrossFade("SuperMegaSword");
                         }
                                 if(BlockMechanic)
                                 {
                                     Blocking.CrossFade("Blocking");
                                     CharacterBlockSoundEffect.PlayDelayed(3);
                                     CharacterBlock.PlayDelayed(3);
                                     CharacterBlock.volume = 4;
                                     CharacterBlockSoundEffect.volume = 3;
                                     CharacterBlockSoundEffect.Play();
                                     CharacterBlock.Play();
                                 }
                                 
 }
 
 function OnGUI()
 {
  var ElapsedTime = ++timer*Time.deltaTime*1
  GUI.Box(new Rect(100, 100, 100, 100) ElapsedTime);
 }
 
 function OnCollisionStay()
 {
     CanYouJump = false;
 }
 
 function LateUpdate()
 {
     transform.rotation = cam;
 }

This is the sword mechanic I'm having trouble with:

                         if(SwordMechanic) 
                         {
                             SwingingSword.CrossFade("SwingingSword");
                             CharacterAttack.Play();                
                         }
                         if(SwordMechanic&&NumberofSwings == TimesSwungSword)
                         {
                             SuperMegaSword.CrossFade("SuperMegaSword");
                         }

It could also be the enemy script prohibiting the attack

 var EnemyHealth : int = 100;
 var TragetTracker : Collider;
 var Player : GameObject;
 var EnemyObject : GameObject;
 var PlayerSword : Rigidbody;
 var EnemyWalkingAnimation : Animation;
 var EightyFightAnimation : Animation;
 var SixtyFightAnimation : Animation;
 var FourtyFightAnimation : Animation;
 var TwentyFightAnimation : Animation;
 var ZeroFightAnimation : Animation;
 
 //numbers are not allowed as variable names
 
 //Got to be precise for the Animations name other wise it won't work
 
 function OnCollisionEnter(PlayerSword)
 {
     if(PlayerSword.contacts)
     {
         EnemyWalkingAnimation.Play();
         EnemyHealth += -5;
     }
 }
 
 function OnTriggerEnter(info : Collider)
 {
     if(info.tag == "Player")
     {
         EnemyObject = GameObject.Find("Player"); 
     }
 
     switch(EnemyHealth)
     {
         //I forgot how switches work, my apologies XD
         //as I remember switches and cases do not require {}. or Cases don't switches do.
         case(EnemyHealth <= 80):
             Debug.Log("I got hit");
             break;
         case(EnemyHealth<=60):
             SixtyFightAnimation.CrossFade("SixtyFightAnimation");
             break;
         case(EnemyHealth<=40):
             FourtyFightAnimation.CrossFade("FourtyFightAnimation");
             break;
         case(EnemyHealth<=20):
             TwentyFightAnimation.CrossFade("TwentyFightAnimation");
             break;
         case(EnemyHealth<=0):
             ZeroFightAnimation.CrossFade("ZeroFightAnimation");
             break;
         default:
             EnemyWalkingAnimation.Play();
             break;
        }
 }
