What does type or namespace error mean?

What is the problem with this code?

public class Healthbar : MonoBehaviour
{
    [SerializeField] private Health playerHealth;
    [SerializeField] private Image totalhealthBar;
    [SerializeField] private Image currenthealthBar;

    private void Start()
    {
        totalhealthBar.fillAmount = playerHealth.currentHealth / 10;
    }
    
    private void Update()
    {
        currenthealthBar.fillAmount = playerHealth.currentHealth / 10;
    }
}

This is the error: The type or namespace name ‘Image’ could not be found (are you missing a using directive or an assembly reference?)

You are probably missing a using statement - in this case, UnityEngine.UI.

Greetings @JP313

The Image class is found in the UnityEngine.UI namespace. Therefore add the following at the top:

using UnityEngine.UI;

I assume you have a Health class defined somewhere because that will throw up an error if you haven’t…
