Hey, only problem i had is i couldn't find the "scene 2, 1" label, but i guess that's because it's not there yet...
So, to do this you need to place the _root.gotoAndPlay("scene2, 1"); within the movie clip of the person where he ends the walk (frame 27?), just on the main timeline somewhere(the same place you have the stop(); command).
You also need to make sure you do not re-keyframe the person, but use standard frames(F5) so that flash doesn't re-initiate the object.
If you wanted the second scene to load on top of the current movie (i don't know how to explain this, but the bio as an overlay) then you could do it using a movie clip as an overlay holder for the scene. For example what i have done in the movie(I've re-uploaded and attached =])...
I threw in a major example of how to do this, but basically what you should be looking at is the AS and where things are placed (and how they reference each other). (Not my on the spot basic design hhaha, which i'm sure will be binned). Anyway, that's how i'd go about it, i also suggest you do some framechecking on your b1 movie clip, basically because if someone rolls over the dude then suddenly clicks he jumps a bit, i've thrown in an example of that aswell...
