Android Build a Simple Android App Basic Android Programming Initializing a Button

It won't let me pass

the question was:Initialize the showFactButton variable using the findViewById() method like the TextView above it. The ID for the button is showFactButton, and don't forget to cast it to a Button with (Button)!

and it shows a error massage: Bummer! There is a compiler error. Please click on preview to view your syntax errors!

import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.TextView;

public class FunFactsActivity extends Activity {

    public void onCreate(Bundle savedInstanceState) {

        // Declare our View variables and assign them the Views from the layout file
        TextView factLabel = (TextView) findViewById(R.id.factTextView);
        ShowFactButton = (Button) findViewById(R.id.showFactButton);

In the preview:./FunFactsActivity.java:16: error: cannot find symbol ShowFactButton = (Button) findViewById(R.id.showFactButton); ^ symbol: variable ShowFactButton location: class FunFactsActivity 1 error

Hi Jude! I see you made a tiny error. You are missing the Button variable type at the beginning of your ShowFactButton declaration.

Thanks !
