Buttons continue to be interactable after setting state to false

[JitteryGamer]

Not sure where I’ve gone wrong - the buttons don’t disable after setting their state to false - any help would be greatly appreciated

using UnityEngine.UI;

public class Quiz : MonoBehaviour
{
    [SerializeField] TextMeshProUGUI questionText;
    [SerializeField] QuestionSO question;
    [SerializeField] GameObject[] answerButtons;
    [SerializeField] int correctAnswerIndex;
    [SerializeField] Sprite defaultAnswerSprite;
    [SerializeField] Sprite correctAnswerSprite;
    
    void Start()
    {
        DisplayQuestion();
    }

    void GetNextQuestion()
    {
        SetButtonState(true);
        DisplayQuestion();
    }
    void DisplayQuestion()
    {
        questionText.text = question.GetQuestion();
        for (int i = 0; i < answerButtons.Length; i++)
        {
            TextMeshProUGUI buttonText = answerButtons[i].GetComponentInChildren<TextMeshProUGUI>();
            buttonText.text = question.GetAnswer(i);
        }
    }

    public void OnAnswerSelected(int index)
    {
        Image buttonImage;
        if(index == question.GetCorrectAnswerIndex())
        {
            buttonImage = answerButtons[index].GetComponent<Image>();
            buttonImage.sprite = correctAnswerSprite;
            questionText.text = "Correct!";
        }
        else
        {
            correctAnswerIndex = question.GetCorrectAnswerIndex();
            string correctAnswer = question.GetAnswer(correctAnswerIndex);
            questionText.text = "Sorry, that's not correct. The answer was;\n" + correctAnswer;
            buttonImage = answerButtons[correctAnswerIndex].GetComponent<Image>();
            buttonImage.sprite = correctAnswerSprite;
        }
        SetButtonState(false);
    }

    void SetButtonState(bool state)
    {
        for(int i = 0; i > answerButtons.Length; i++)
        {
            Button button = answerButtons[i].GetComponent<Button>();
            button.interactable = state;
        }
    }
}

OOOPS had a greater than sign instead of a less than sign.
