flash actionscript: If I had a SO created in a user.swf which held user info, on completion of the
user filling in the form the info gets flushed to the SO and then the index.swf
loads a new movie titled main.swf. How would i send info from the main.swf to
the SO created by the user.swf? i.e. how would i reference the SO in a
different movie to access it? Do I need to define it again in the new movie or
would something like _root.so.data.myobject etc suffice?????

You still need to let this movie know you want to access that file...

So just like we did in the first movie :

so = sharedObject.getLocal("mySo","/"); // where mySo is the name of the .sol
file created in the original .swf

then it becomes available to this movie also

cheers,
