Brain Fart Question

I’m trying to do a really simple flash movie. 3 buttons each on loads a new movie clip into a holder that is on the stage.

I was just going to use this code:


on (release) {
    MCHolder.loadMovie("loader.swf", 1);
}

and place it on the buttons, since they have a up, over and hit state. But when I test the movie I get this error:

1087: Syntax error: extra characters found after end of program.

I have do something like this before but can’t figure out what the simple error I’m maying here.

Also what is the easiest way to make a button stay on the down or hit state when the movie associated with it has loaded?
