Question very new to this c#

I am trying to do this

but the options on the component are not the same.
here is my code

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

public class EnemySpawner : MonoBehaviour
{
public GameObject enemy;
float randX;
Vector2 whereToSpawn;
public float spawnRate = 2f;
float nextSpawn = 0.0f;

void Start()
{

}

// Update is called once per frame
void Update()
{
if (Time.time > nextSpawn)
{
nextSpawn = Time.time + spawnRate;
randX = Random.Range (-8.4f, 8.4f);
whereToSpawn = new Vector2 (randX, transform.position.y);
Instantiate(enemy, whereToSpawn, Quanternion.identify);
}
}
}

Welcome to the forum!
Please use Code Tags for code, so it's easier to read - and more likely you will get a reply! (Not everyone is willing to format it for you, like I am.)

This is what your code would look like with them:

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4.  
5. public class EnemySpawner : MonoBehaviour
6. {
7.     public GameObject enemy;
8.     float randX;
9.     Vector2 whereToSpawn;
10.     public float spawnRate = 2f;
11.     float nextSpawn = 0.0f;
12.  
13.     void Start()
14.     {
15.  
16.     }
17.  
18.     // Update is called once per frame
19.     void Update()
20.     {
21.         if (Time.time > nextSpawn)
22.         {
23.             nextSpawn = Time.time + spawnRate;
24.             randX = Random.Range (-8.4f, 8.4f);
25.             whereToSpawn = new Vector2 (randX, transform.position.y);
26.             Instantiate(enemy, whereToSpawn, Quanternion.identify);
27.         }
28.     }
29. }

Now that it's easier to read, let's see where the problem is:
You made a spelling error in line 26. Quanternion.identify should be Quanternion.identity

If that's not it please check the following:
Do you still have have any errors showing in the Console Window? If so, what do they say?
Please create a screenshot showing all of them, or copy paste them here.

 

Also, how to report problems productively in the Unity3D forums:
