Question Parameter 'Jump' does not exist. UnityEngine.Animator:SetTrigger (string)

using UnityEngine;

public class PlayerMovement : MonoBehaviour

if (horizontalInput > 0.01f)
transform.localScale = Vector3.one;

//Wall jump logic

body.velocity = Vector2.zero;
}
else
body.gravityScale = 7;

if (Input.GetKey(KeyCode.Space))
Jump();
}
else

}

private void Jump()
{

}
else if (onWall() && !isGrounded())

}
else
body.velocity = new Vector2(-Mathf.Sign(transform.localScale.x) * 3, 6);

wallJumpCooldown = 0;
}
}

private void OnCollisionEnter2D(Collision2D collision)
{
}

private bool isGrounded()
{
RaycastHit2D raycastHit = Physics2D.BoxCast(boxCollider.bounds.center, boxCollider.bounds.size, 0, Vector2.down, 0.1f, groundLayer);
return raycastHit.collider != null;
}
private bool onWall()
{

return raycastHit.collider != null;
}
}


It says
Parameter 'Jump' does not exist.
UnityEngine.Animator:SetTrigger
Parameter 'Jump' does not exist.
UnityEngine.Animator:SetTrigger

 

What should i do?
