Calling Loaded Movie (MovieNum) with Variable??

Hi,

Is there a good way to load a Movie with a variable name.

Here's my script:

loadMovieNum("firstmovie", 1)
loadMovieNum("secondmovie", 2)
loadMovieNum("thirdmovie", 3)

Then I have a frame to make the movies play

_level1.play

What I'm trying to do is use a variable to replace the "1" in "_level1" e.g. _levelvariable.play();

Does this make ANY sense?
Thanks a lot for reading this.
