Coin flip counter

Im trying to make a 3d coin flipper that counts total flips, heads, and tails. Im pretty new to this so any help is appreciated.

using UnityEngine; using UnityEngine.UI;

public class ScoreTracker : MonoBehaviour {

 public int totalFLips;
 public int heads;
 public int tails;
 public Transform coin;
 public Text flipText;
 public Text flipTextTwo;
 public bool landed;

    
 // Start is called before the first frame update
 void Start()
 {
     totalFLips = 0;
     heads = 0;
     tails = 0;
 }

 // Update is called once per frame
 void Update()
 {
     

     flipText.text = coin.transform.position.y.ToString("0");
     flipTextTwo.text = coin.transform.rotation.x.ToString("0");
     int.Parse(flipText.text);
     int.Parse(flipTextTwo.text);

     if (flipText.text == "0")
     {
         landed = true;
     }
     else if (flipText.text != "0")
     {
         landed= false;
     }

     if (landed == true & coin.rotation.x == 90)
     {
         heads += 1; 
         Debug.Log("Heads");
         
     }
     else if (landed == false & coin.rotation.x == -90)
     {
         tails += 1;
         Debug.Log("Tails");
     }

     //Debug.Log(flipText);
 }

 void flipTotal()
 {
     totalFLips += totalFLips;
 }

 

}
