Changing a Prefab's Script's Variables

Questions & Answers
1

I have a card Prefab with a couple of variables: public string cardName and public byte index. Other information is generated based on those values for an instance of said Prefab. In a different controller, I have a function that’s trying to create unique cards from that Prefab:

public GameObject cardPrefab
void makeCard(byte index)
{
    GameObject newCard = Instantiate(cardPrefab ...)
    newCard.name = "Testing";
    PrefabScript cardScript = newCard.GetComponent<PrefabScript>();
    cardScript.cardName = "Useful_Item";
    cardScript.index = 30;
}

From simple testing, this works up until I attempt to access the PrefabScript (which is a Component of the Prefab), which returns NULL somehow. Why?

If the prefab has the PrefabScript component, that should work. Could you check in the hierarchy if the instantiated prefab have this component?
