Prob importing swf's

hi :),
i have a problem importing external swfs into my movies… when i do… they only show up as pictures… none of the action script works:( like i have actionscript telling it to go back to frame 12, and it doesnt at all, just carries on playing… like it sees it as a graphic? i tried chaning it to movie clip in library but still no… help, i’m v.confused. thnx
