Why my 2D Sprite runing Animation only works when i move to the left? HELP PLS

Hi im new on all this wolrd of developing 2d games on Unity. In a couple days i designed a couple characters pixel based and i made an animation that simulate the player runing. Now my player can move to the left and right and thats cool but also added my running animation when i press "A" to the left and "D" to the right, here is where the problem comes. I watched some tutoriales to do this possible but actually the runing animation only works when i press the "A" but when i press "D" the runing animation didnt work :/ Here is my code at the moment, i hope and someone can help me it would be awesome, thanks and good day :p or if someone know a different way to do it I'd really appreciate it.

 // Start is called before the first frame update
 void Start()
 {
    
 }

 // Update is called once per frame
 void Update()

 {
  if (Input.GetKey(KeyCode.D))

  {
      pos.position += new Vector3(1f, 0, 0) * speed * Time.deltaTime; 
      buttle.flipX = false;
      anim.SetBool("caminarder", true);
      
  } else {
   anim.SetBool("caminarder", false);
 }
        
  if (Input.GetKey(KeyCode.A))

        {
              pos.position -= new Vector3(1f, 0, 0) * speed * Time.deltaTime;
              buttle.flipX = true; 
              anim.SetBool("caminar", true);
        } else{
              anim.SetBool("caminar", false);
        }

        if (Input.GetKeyDown(KeyCode.Space))

        {
              sal.AddForce(Vector2.up * fsal, ForceMode2D.Impulse);
      
  }
  }
  }
