Linking code to simple button/textbox within mc

Hey all,

Attached is a file with a simple flash button within an mc. I am having trouble linking the code on the root timeline to a textbox within an mc that changes depending on what is happening to the button.

Anyone have an idea of why it’s not working?

stop();

this.tutButton.txtBox.text = "Up"
this.tutButton.exampleBtn.onRollOver = function() {
    this.tutButton.exampleBtn.txtBox.text = "Over"
}
this.tutButton.exampleBtn.onPress = function() {
    this.tutButton.exampleBtn.txtBox.text = "Down"
}
this.tutButton.exampleBtn.onRollOut = function() {
    this.tutButton.exampleBtn.txtBox.text = "Up"
}
