Determine a labelled frame from a swf?

Hi:

Let’s say I have .swf A and B. Swf B is loaded into a mc in swf A through loadMovie. Both swf A and B have labelled frames in them.

Is there a way that swf A can determine if swf B is on a particular named (labelled) frame? For instance, when swf B (is loaded into swf A) and swf B reaches a certain labelled frame, I want swf A to be able to determine that and then do something.

Does that make sense?

Thanks,
Loren
