here’s my codes:

    [SerializeField]
    public TextMeshProUGUI resulttxt;
    [SerializeField]
    public TextMeshProUGUI explanationtxt;
    private string infp;


    void Start()
    {
        resulttxt.text = PlayerPrefs.GetString("typeA") + PlayerPrefs.GetString("typeB") + PlayerPrefs.GetString("typeC") + PlayerPrefs.GetString("typeD");
        ExplainType();
    }

    void ExplainType()
    {
        if (resulttxt = "INFP")
        {
            infp = "ate angel ganda";
            explanationtxt.text = infp;

        }

if (resulttxt = “INFP”)

should be

if (resulttxt.text == “INFP”)
