Unity error CS1014

So I’m watching a tutorial on how to make own FPS game, because I want to learn Unity but I get this error message but the person in the video not. I’m still new to C# and I can’t figure out what’s wrong… Here is the code:

using UnityEngine;
using System.Collections;

public class bullet_ThermalDetonator : MonoBehaviour {

	float lifespan = 3.0f;

	// Use this for initialization
	void Start () {
	// Update is called once per frame
	void Update () {
		lifespan -= Time.deltaTime;

		if(lifespan <= 0) {

	void OnCollisionEnter(Collision collision) {

				if (Collision.gameObject.tag == "Enemy") {
						Destroy (collision.gameObject);
						Destroy (gameObject);

	void Explode {



‘Explode’ on line 30 needs the ‘()’ appended:

void Explode() {

On line 32, ‘Destroy’ is misspelled.

On line 24, ‘collision’ needs use the lower case ‘c’ to refer to the variable rather than the class:

   if (collision.gameObject.tag == "Enemy") {
