I have a bug with my UI.

I have a UI bug. My radiation on go up it did, but I must have changed something and can't remember what I did. If some could help, here is my code: using UnityEngine; using UnityEngine.UI; using UnityStandardAssets.Characters.FirstPerson;

public class PlayerVitals : MonoBehaviour {

 [SerializeField] private Transform player;
 [SerializeField] private Transform respawnPoint;

 public Slider healthSlider;
 public int maxHealth;
 public int healthFallRate;
       
 public Slider thirstSlider;
 public int maxThirst;
 public int thirstFallRate;

 public Slider hungerSlider;
 public int maxHunger;
 public int hungerFallRate;

 public Slider radiationSlider;
 public int maxRadiation;
 public int radiationGainRate;

 public Slider staminaSlider;
 public int maxStamina;
 private int staminaFallRate;
 public int staminaFallMultiplier;
 private int staminaRegenRate;
 public int staminaRegenMultiplier;

 private CharacterController charController;
 private FirstPersonController playerController;

 void Start()
 {
     healthSlider.maxValue = maxHealth;
     healthSlider.value = maxHealth;

     thirstSlider.maxValue = maxThirst;
     thirstSlider.value = maxThirst;

     hungerSlider.maxValue = maxHunger;
     hungerSlider.value = maxHunger;

     staminaSlider.maxValue = maxStamina;
     staminaSlider.value = maxStamina;

     staminaFallRate = 1;
     staminaRegenRate = 1;


     radiationSlider.maxValue = 0;
     radiationSlider.value = maxRadiation;

     charController = GetComponent<CharacterController>();
     playerController = GetComponent<FirstPersonController>();
 }

 void Update()
 {
     //Health Controller
     if (hungerSlider.value <= 0 && (thirstSlider.value <= 0) && (radiationSlider.value >= maxRadiation))
     {
         healthSlider.value -= Time.deltaTime / healthFallRate * 2;
         Debug.Log("Dying");
     }

     else if(hungerSlider.value <= 0 || thirstSlider.value <= 0 || radiationSlider.value >= maxRadiation)
     {
         healthSlider.value -= Time.deltaTime / healthFallRate;
         Debug.Log("Dying");
     }

     if(healthSlider.value <= 0)

     }
