Accessing Storyline Variables from Inserted SWF

I would like to be able to access variables in the Storyline story.swf from my own swf that is inserted on a screen. It appears that all of the variables in the Player class are protected so I can't access them directly from my swf.

Is there a documented list of variables that can be accessed through JavaScript and the GetPlayer().GetVar("foo") interface?

Has anyone had any luck using ExternalInterface in an embedded swf for this purpose? When I try:

trace(ExternalInterface.call("GetVar","myVarName");

I get undefined, presumably because the GetVar() function is scoped within the Storyline swf and requires the GetPlayer().GetVar syntax. I've tried assigning GetPlayer() to an object within my swf and then trying GetVar("foo") on the object with no positive results.

It seems like I'll have to link my own js file into the story.html file, with a function that exposes GetVar() something like:

function myGetVar(_varName){

    var player = GetPlayer();

     return player.GetVar(_varName);

}

If this works then it raises the issue of having to add the link to the .js file to the story.html file each time I publish (and add the .js file to the output folder as well).

Is there a template for the story.html file that Storyline uses that I could add the .js link to as a permanent fix?

Lastly, is this the correct forum for asking these questions? If not, where?

Thanks,
