Initialization of leftScore/rightScore Lesson 10 in 28-day

I’m wondering why leftScore and rightScore don’t get initialized in the lesson 10 tutorial for the war card game. When I don’t initialize them my XCode yells at me, but it doesn’t look like Chris initialized them anywhere?
Here’s my code:

class ViewController: UIViewController {

@IBOutlet weak var leftImageView: UIImageView!

@IBOutlet weak var rightImageView: UIImageView!
@IBOutlet weak var leftScoreLabel: UILabel!
@IBOutlet weak var rightScoreLabel: UILabel!

override func viewDidLoad() {
    // Do any additional setup after loading the view.

@IBAction func DealButtonView(_ sender: Any) {
    print("Deal Tapped")
    let leftNum = Int.random(in: 2...14)
    let rightNum = Int.random(in:2...14)
    leftImageView.image = UIImage(named: "card\(leftNum)")
    rightImageView.image = UIImage(named: "card\(rightNum)")
    if rightNum > leftNum {
        rightScore += 1
        rightScoreLabel.text = String(rightScore)
    } else if leftNum > rightNum{
        leftScore += 1
        leftScoreLabel.text = String(leftScore)
    } else{
        //do nothing

If this forum isn’t the right place for this question let me know, and I’ll put it somewhere else :slight_smile:

Figured it out! I realized that I needed to create global variables, and I missed that part in the tutorial
