loadMovie

Ive got a little bit of problem here ive built a function that loads and positions movieclips onto the stage from the libary using a void datatype with attachmovie . now id like to use loadMovie to load an external swf and pass it through my function which uses attachmovie

the problem is the loaded swf isnt in the libary at all when i try to attach it with its instance name i get nothing .

Annyone knows a workaround ?
thanks
