Set loadmovie URL in external movie

is it possible to set a variable for a movieclip URL, for example

set(clipname, “test.swf”)

then refer to that variable when the movie that holds this action is loaded into the main movie? ei.

loadmovie(“clipname”, 2)

basically what i want to do is only set up the content loading sequence once in the main movie and use script to load the respective content for a button in a loaded navigation movie, i think that makes sense.

any help or advise would be most appreciated. thanks anyone and everyone.
