FMX - communicating diff swf in html

Is there a way to communicate two separate swf files in an html?

Let’s say those 2 swfs are in cells of a table. (There isn’t a holderMovie that loads those two, I know that would solve it but I’d like to keep the two files separate).
Let’s say one swf movie is a navigation bar and the other is the content holder. That content holder has a mc called content.
How do you call from a button of the nav to that content mc in the other swf…is it possible??? Let’s say we are loading an external swf to that content mc from the nav to the content holder.
