Make clickable link in menu with kotlin

I try to make a Bottom navigation, I have this code 

val bottomNavigation = findViewById<View>(R.id.bottom_navigation) as 
  BottomNavigationView
    bottomNavigation.setOnNavigationItemSelectedListener { item ->
        when (item.itemId) {

            R.id.botom__nav__home ->
                // Action when tab 1 selected
                val intent = Intent(this, HomeActivity::class.java)
            R.id.botom__nav__profile ->
                // Action when tab 2 selected
                val intent = Intent(this, LikeActivity::class.java)
            else ->
                // Action when tab 3 selected
                val intent = Intent(this, ProfileActivity::class.java)
        }
        true
    }
    startActivityForResult(intent, 99)
}

I have these errors:

' Expecting an expression '
' Expecting "->" '

For each element in the " When " ...

Can somebody help me to fix these errors?

Please remove the item -> in this line 

bottomNavigation.setOnNavigationItemSelectedListener { item ->
    when (item.itemId) {`

The problem is that you declare val intent various times inside the when block. To solve this just move the declaration of the intent outside of your when block, for example like this:

lateinit var intent:Intent
bottomNavigation.setOnNavigationItemSelectedListener { item ->
    when (item.itemId) {

        R.id.botom__nav__home ->
            // Action when tab 1 selected
            intent = Intent(this, HomeActivity::class.java)
        R.id.botom__nav__profile ->
            // Action when tab 2 selected
            intent = Intent(this, LikeActivity::class.java)
        else ->
            // Action when tab 3 selected
            intent = Intent(this, ProfileActivity::class.java)
    }
    true
}
startActivityForResult(intent, 99)
