SmoothMoves C# Animation Problem

Hi,

I am new to unity (and coding in general) and have been having some issues with getting one of my animations to play. Here is a section of my code and I will explain what is happening after...

void Update () {

     CharacterController player = GetComponent < CharacterController > ();
 
     if (player.isGrounded)
     {
     velocity = new Vector3 ( Input.GetAxis ( "Horizontal" ),0,0);
         
     RunningConditionsAndAnimation();
     CrouchingConditionsAndAnimation();    
     }

     velocity.y -= gravity * Time.deltaTime;
     player.Move (velocity * Time.deltaTime);    

}

     void RunningConditionsAndAnimation ()
     {
         if (velocity.x > 0)
         {
             velocity.x = runSpeed;
             explorerAnimation.Play ( "Run" );    
             print ( "Run Right");
         }
         if (velocity.x < 0)
         {
             velocity.x = -runSpeed;
             explorerAnimation.Play ( "Run" );    
             print ("Run Left");
         }
     }
         

void CrouchingConditionsAndAnimation ()

{

         if (velocity.x == 0 && Input.GetAxis ( "Vertical" ) < 0)
         {
             explorerAnimation.Play ( "Crouch" );    
             print ("Crouch");
         }

}

If I press the down arrow, the console will print "Crouch" but my crouching animation will not play. Also, if I put any other line of code that is not an animation in CrouchingConditionsAndAnimations() it will work just find. I know there is nothing wrong with my crouch animation because if I replace "Run" with "Crouch" in RunningConditionsAndAnimations(), it plays. This is all based on the Walker Boy's Mario 2D tutorials so maybe I did something wrong turning the javascript into C#. I have spent some time looking for an answer online and have rewritten my code many times but I cannot get it to work. Any help would be appreciated.
