Modding Question: How to call Papyrus functions from within Flash?

[pipdude]

This is a second question related to my project to understand communication between Skyrim and its custom Flash UI elements. First question here: http://www.loverslab.com/topic/55116-modding-question-how-to-capture-gamepad-input-within-custom-flash-ui-element/

 

I am able to successfully load a custom swf. I am also able to run Flash functions from Papyrus via the various invoke calls. However, I haven't figured out how to run Papyrus functions from Flash.

 

I'm using the SkyUI source as a guide. The GameDelegate class seems like it might be what I need. But, the usage I've seen so far in the code doesn't demonstrate how to reference custom functions on a specific script. It just calls functions like "PlaySound", the foundational script it is calling that on is a mystery to me.

 

Any help would be greatly appreciated!
