alt textHello, sorry for my English…
I got this error, it tells me that it can’t find the parameter… the parameter is done, I don’t understand why it can’t find it…

public class PlayerMove : MonoBehaviour
{
public float runSpeed = 2;

public float jumpSpeed = 3;

Rigidbody2D rb2D;

public bool betterJump = false;

public float fallMultiplayer = 0.5f;

public float lowJumpMultiplayer = 1f;

public SpriteRenderer spriteRenderer;

public Animator animator;

void Start()
{
    rb2D = GetComponent<Rigidbody2D>();
}


void FixedUpdate()
{
    if (Input.GetKey("d") || Input.GetKey("right"))
    {
        rb2D.velocity = new Vector2(runSpeed, rb2D.velocity.y);
        spriteRenderer.flipX = false;
        animator.SetBool("Run", true);
    }

    else if(Input.GetKey("a") || Input.GetKey("left"))
    {
        rb2D.velocity = new Vector2(-runSpeed, rb2D.velocity.y);
        spriteRenderer.flipX = true;
        animator.SetBool("Run", true);
    }

    else
    {
        rb2D.velocity = new Vector2(0, rb2D.velocity.y);
        animator.SetBool("Run", false);

    }

The error means your Animator Controller doesn’t have a bool parameter called “Run”, example:
