How to control the main timeline from within a symbol?

Question

I have a small world map as a symbol called "verden" and I want the user to click Europe, Asia, or Africa and jump to named labels in the main timeline.

On the main timeline a have the label "intro" with a Stop action and the label "europa". At label "europa" I have a symbol also called "europa" which has a display of None at label "intro" and On at the label "europa".
The animation never goes to label "europa"
I have this code on europa in the symbol "verden" :
// insert code for mouse click here
sym.getComposition().getStage().getSymbol("europa").play("europa");
The files are on Dropbox here
Update, now it works:
sym.getComposition().getStage().play("europa");

Hi Bill,
There are plenty of threads on here about scope, but here's one way to create a global variable:
// code on Stage.compositionReady
sym.myGlobalVar = 1;
Then, anywhere in your project, you can check/set that var like so:
sym.getComposition().getStage().myGlobalVar = 2;
And here's one way to create a global function:
// code on Stage.compositionReady
sym.myGlobalFunction = function(){
          console.log('myGlobalFunction');
Then, anywhere in your project, you can call that function like so:
sym.getComposition().getStage().myGlobalFunction();
