안녕하세요.

Firebase회원가입 구현 강의의 8:00 따라 하고 있습니다.

activity_join.xml에서 아이디 다 추가주었는데 이렇게 뜨네요

Unresolved reference: passwordArea2

private lateinit var auth: FirebaseAuth

    private lateinit var binding: ActivityIntroBinding

    override fun onCreate(savedInstanceState: Bundle?) {

        super.onCreate(savedInstanceState)

        auth = Firebase.auth

        //setContentView(R.layout.activity_join)

        binding = DataBindingUtil.setContentView(this, R.layout.activity_join)

        binding.joinBtn.setOnClickListener {
            val email = binding.emailArea.text.toString()
            val password1 = binding.passwordArea1.text.toString()
            val password2 = binding.passwordArea2.text.toString()

            // 저기 값이 비어있는지 확인
            if (email.isEmpty()){
                Toast.makeText(this, "이메일을 입력해주세요", Toast.LENGTH_LONG).show()
            }
            if(password1.isEmpty()){
                Toast.makeText(this, "password1을 입력해주세요", Toast.LENGTH_LONG).show()
            }
            if(password2.isEmpty()){
                Toast.makeText(this, "password2을 입력해주세요", Toast.LENGTH_LONG).show()
            }
            if (!password1.equals(password2)){
                Toast.makeText(this, "비밀번호을 똑같이 입력해주세요", Toast.LENGTH_LONG).show()
            }
        }
    }

private lateinit var binding: ActivityIntroBinding

으로 입력했었네요. Join으로 고쳐서 해결했습니다!
