How to assign Instantiated object through script?

Hello. I have a script called “DestroyGameObject_10s”. So that’s what I have right now:

    ## DestroyGameObject_10s.cs ##
	public GameObject road;
	public GameObject myCar;

	void Start () {
		myCar = GameObject.Find("car");
		road = RoadSpawn.road; // THIS DOESN'T WORK
	}

And the other script called “RoadSpawn.cs”

void SpawnRoad(){
		spawnedRoad = (GameObject)Instantiate(road, new Vector3(startRoadX + roadXCoordinates, road.transform.position.y, road.transform.position.z), Quaternion.Euler(0,0,0));
		spawnedRoad.AddComponent<DestroyGameObject_10s>();
		roadXCoordinates += 12;
	}

So I want this Instantiated object called spawnedRoad to assign through script. But it doesn’t work. Why?

I used RoadSpawn.road;
I used RoadSpawn r = new RoadSpawn(); r.road;

But it doesn’t work :frowning:
Thanks in advance.

AddComponent returns the component it added. So :

DestroyGameObject_10s dgo = spawnedRoad.AddComponent<DestroyGameObject_10s>();
dgo.road = theRoad; // replace with your reference
dgo.myCar = theCar; // replace with your reference
