Kotlin for android - first button works, second doesn't?

im trying to code a really simple app, it's my first one for android. In the console i don't get any error messages but when i try to run the app on android emulator i can only press the first button and get to the activity i want, second doenst work. Maybe you can help me. Thats my code:

    val button = findViewById<Button>(Btn)
    button.setOnClickListener {
        val intent = Intent(this, MainActivity2::class.java)
        startActivity(intent)

        val button = findViewById<Button>(Btn2)
        button.setOnClickListener {
            val intent = Intent(this, MainActivity3::class.java)
            startActivity(intent)

        }
    }
}

}

What am i missing? Thank you in adavance!
