Apple Picker Prototype (Changing direction error) [solved]

Unity Engine
1

Hi, I am trying to make a game based on the apple picker prototype mentioned
in the book introduction to Introduction to Game Design, Prototyping, and Development. But changed apple tree to snowman and snowballs.

/The /basic movement part works but when I add the //changing direction part of the script I get errors.
Help appreciated.

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class SnowController : MonoBehaviour
{
    public GameObject SnowballPrefab;

    public float speed = 1f;

    public float leftAndRightEdge = 10f;

    public float chanceToChangeDirections = 0.1f;

    public float secondsBetweenSnowballDrops = 1f;

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

    // Update is called once per frame
    void Update()
    {
        //basic movement
        Vector3 pos = transform.position;
        pos.x += speed * Time.deltaTime;
        transform.position = pos;

        // Changing Direction
        if (pos.x < -leftAndRightEdge) // move right
        {
            speed = Mathf.Abs(speed);
        }
        else if (pos.x > leftAndRightEdge) // move left
        {
            speed = -Mathf.Abs(speed);

        }
}

You are missing a closing brace } on your Update method
