External swf's

hello, im loading external swf’s on my main stage,… with buttons know my questions is, is there a way to load and external movie with, example
button1. load external movie1… and with buton 2 tell the external movie 1 to gotoandplay frame(30) or something like that. ??

what i have in external movie 1… is in first 20 frames… some transitions of the movie appearing and on in frame 30 to 40 y have the same animation but reversed… so i woul look like its disappering… so what i want is that when i click another button… my previous movie (external movie1) unloads with transition and then load my other movies.

hope u understand :to:
