VBox not displaying

Hey Guys I think I might have an issue with my IDE. I'm working through the JavaFX program with Craig and can't seem to get the code to render correctly. It's verbatim what's in the video. The problem I'm seeing on my end: The Scene is not setting up correctly. It renders as if the VBox is not present.

I'm still not getting a layout to show up on my intellJ idea install. I'll include the code for your reference. Another strange thing. When searching for {idea stage javafx not working} I'm only recieving 169 results from both google and Duck Duck Go. Any Ideas what might be going on or who to kill/shoot first?

package sample;

import javafx.application.Application;
import javafx.fxml.FXMLLoader;
import javafx.scene.Group;
import javafx.scene.Parent;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.control.TextField;
import javafx.scene.layout.VBox;
import javafx.scene.text.Text;
import javafx.stage.Stage;



public class Main extends Application {

    @Override
    public void start(Stage primaryStage) throws Exception{
        //Parent root = FXMLLoader.load(getClass().getResource("sample.fxml"));
        Group root = new Group();
        Text txt = new Text("Sup");
        TextField nameFld = new TextField();
        Button btn = new Button();
        btn.setText("Say Sup!");
        btn.setOnAction(evt -> System.out.printf("Sup %s!%n",
                nameFld.getText()));
        txt.setY(50);
        VBox box = new VBox();
        box.getChildren().addAll(txt, nameFld, btn);
        root.getChildren().add(txt);
        root.getChildren().add(btn);
        primaryStage.setTitle("Sup");
        primaryStage.setScene(new Scene(root, 300, 275));
        primaryStage.show();
    }


    public static void main(String[] args) {
        launch(args);
    }
}

comment out: root.getChildren().add(btn); root.getChildren().add(txt);

and substitute in: root.getChildren().add(box);
