Canvas Slider Max Value / High Value Help

I have a script where an object on collision updates the max hit points for the player. The value goes up but the maxValue on the slider does not go up.

I have added the “using unityEngine.UI”

but I cannot figure out the reference to the max value. How can I update the slider…

Object in project
Canvas

HealthBar

LevelManager.cs
   void HealthIncrease(int exthealth)
	{
		LevelManager.instance.maxHealth += exthealth;
		LevelManager.instance.healthBar.SetHealth(LevelManager.instance.currentHealth);


healthbar.cs
public class HealthBar : MonoBehaviour
{

	public Slider slider;

	public Gradient gradient;
	public Image fill;

	void Start()
	{
		slider.minValue = 0;
		slider.maxValue = 7;
	}
	public void SetMaxHealth(int health)
	{
		slider.maxValue = health;
		slider.value = health;

		fill.color = gradient.Evaluate(1f);
	}

    public void SetHealth(int health)
	{
		slider.value = health;

		fill.color = gradient.Evaluate(slider.normalizedValue);
	}

Figured it out. Had the code in the wrong position on the slider.

public void SetHealth(int health)
{
	slider.value = health;

	fill.color = gradient.Evaluate(slider.normalizedValue);

	if (LevelManager.instance.maxHealth > slider.maxValue)
	{
		slider.maxValue = LevelManager.instance.maxHealth;
	}
}
