Loading movie clips on start

anyone have the correct syntax for this:

When my movie starts, i want 3 external swf files to open into specific areas on my main stage. (i made 3 movie clips on the stage where i want the movies to load and named them (for example)clip1, clip2, and clip3

i know how to get the movie to load using a button, but cannot get the movies to load when the movie starts. It keeps telling me i need an ON handler.
