Java with SceneBuilder 2.0:

I'm using Scene Builder 2.0 to create a Java FXML. I'm using radio buttons, but for some reason I can't get the radio button selection to change the label I want. All I'm trying to do at this point is tie the buttons to a label text change. I do have the radio buttons tied to a toggle group called group in the Sample.fxml tab. The label I'm trying to change the text of is the lblOutputLabel.

Sample.fxml tab
