Access Label in Nested Symbol

Hello All;

OK. Here we go.

Project is laid out like so

Stage

MainMenu (Symbol)

   SubMenu1 (Symbol)

Within the MainMenu, I have a Label (ShowSub1)

The MenuItem under the MainMenu, when clicked, needs to activate the label (ShowSub1)

However, I cannot seem to access the Symbols.

This is the code that I have tried.

Access all Symbols

sym.getComposition().getStage().getSymbol('MainMenu').getSymbol("SubMenu1").play('ShowSub1 ')
Also tried this as well
sym.getComposition().getStage().getSymbol("SubMenu1").play('ShowSub1')

I need to Access the SubMenu Symbol and Label from within the MainMenu.

Any assistance on this would be great.

Thanks

Wayne
