Help!!!!!!!!! compilation gone wrong What is wrong here?

import android.app.Activity
import android.os.Bundle
import android.widget.TextView
import android.widget.RelativeLayout

class MealActivity : Activity() {
  override fun onCreate(savedInstanceState: Bundle) {


    val foodLabel = findViewById(R.id.foodTextView) as TextView
    val drinkLabel = findViewById(R.id.drinkTextView) as TextView
    val mealLayout = findViewById(R.id.mealLayout) as RelativeLayout
    mealLayout.backgroundColor = Color.RED
    foodLabel.settextColor = Color.BLUE
    drinkLabel.settextColor = Color.GRAY


Make sure to capitalize 'Text' when using 'setTextColor'. That being said, it still doesn't work. I am flummoxed as well. I've tried what you've got and I was sure it was right. I tried using foodTextView in lieu of foodLabel. I tried using setTextColor(Color.BLUE) instead. I've tried all sorts of wrong answers, but I am absolutely sure the right one is

    foodLabel.setTextColor = Color.BLUE
    drinkLabel.setTextColor = Color.GRAY

But it says it's wrong! I'm confused.

The syntax we're to use is actually

foodLabel.textColor = Color.BLUE
drinkLabel.textColor = Color.GRAY

I don't know where in the lesson it says that, but this was answered elsewhere and that was what worked.
