I've followed the lessons to the letter but Unity doesn't work

Hello, I'm new in Unity.

I'm following the lesson track on the basics on making a videogame, but I'm stuck in a few points.

Mainly is the code. I've copied the lessons and rechecked, but often it leaves me with parse errors (unexpected symbols) or can't apply values to float anymore (stuck to nul for some reason). As an example I have a script from Object-Oriented Prog. in Unity course:

using UnityEngine; using System.Collections;

public class MovingTarget : Target {

[SerializeField]
private float amplitude = 1f;

[SerializeField]
private float timePeriod = 1f;

private Vector3 startPosition;

private bool movement = true

// Use this for initialization
protected override void Start () {                             (unexpected symbol "protected")

    base.Start ();

    // Store the start position
    startPosition = transform.localPosition;                (unexpected symbol "=")

}


void LateUpdate () {                                                  (unexpected symbol "void")

    if (Moving) {

        // Calculate theta
        float theta = Mathf.Sin (Time.timeSinceLevelLoad / timePeriod);

        // Create the new delta position
        Vector3 deltaPosition = new Vector3 (amplitude, 0f, 0f) * theta;

        // Update the position by adding the start position and delta position
        transform.localPosition = startPosition + deltaPosition;

    }

}


    protected override void OnCollisionEnter (Collision other) {

    if (other.gameObject.ComareTag("Arrow")) {

        moving = false;

    }

    base.OnCollisionEnter (other);

}

public override void DestroyTarget() {

    // Disable target movement
    moving = false;

    base.DestroyTarget ();

}

}

I don't get what I'm doing wrong. Is it some compatibility issue?
