Accessing symbols inside of adaptive containers

Question

Hello, thank you for taking the time to read my question.
I found one thread that discusses basically what I am trying to do, but the solutions didn't work for me and it looks like it didn't work for the original poster.  The link to this discussion is:  Re: Symbol accessible inside adaptive container?  I am using the edgecommons script to load either 'layout1080' or 'layout600' into a symbol on the main stage called 'adaptiveContainer' depending on the width of the web browser.  This all works great, and I can control the playhead from within either 'layout1080' or 'layout600' (by using getParentSymbol) but when I try to access it from a button within 'adaptiveContainer' or on the stage, I have no luck with any of the solutions I have tried. 
User elainfinnel had what looked to be a good solution, but after trying it I can't get it to work.  Their suggestion was:
In the symbol definition, add a creationComplete event and add the following line:
sym.getParentSymbol().setVariable("currentSymbol", sym);
Then, in your Stage, you can access the symbol by doing this:
var mySymbol = sym.getSymbol("currentSymbol");
You can then refer to it as a symbol:
mySymbol.play("myLabel");
This seemed like a great solution to the problem I am having, but I can't seem to get it to work.  When I inspect the element in firefox I can see the div class for 'adaptiveContainer' (div id="Stage_adaptiveContainer") but the div id for either 'layout1080' or 'layout600' doesn't show.  The div id displays as a number (i.e. div id="Stage_##") that is generated at some point during the script.  I am up to 53 now, and it changes every now and then.  There doesn't seem to be any sign of the div id for 'layout1080' anywhere. 
Thanks for reading and any help is greatly appreciated!

It needs a little modification
//In the symbol definition of layout1200,layout800, add a creationComplete event and add the following line:
var parent = sym.getParentSymbol().getParentSymbol();
parent.setVariable("currentSymbol", sym);
//Then, in your Stage, you can access the symbol by doing this:
var mySymbol = sym.getVariable("currentSymbol");
mySymbol.play("myLabel");
