its more than likely how the answers are referenced in your
quiz file. On the _root timeline these are all the same
Once you import "Quiz.swf" it no longer is on the _root
level. I'd just look through the file looking for references to
where the answers reside. If its what I think it is, you'll just
have to replace "this" with "this._parent" a few times or
something. --But not everywhere, just in specific places.
