im trying to, to make my MC have a rollover effect but my movie clip had been added by Action Script so this doesnt work
pane.onRollOver = over;
pane.onRollOut = out;
function over() {
this.gotoAndPlay(2);
}
function out() {
this.gotoAndPlay(7);
}
or can you refer by linkage ID?

you must use attachMovie for movies from library so you can reference them in ActionScript code

When you call MovieClip.attachMovie you must make a name for it.
```auto
attachMovie(idName:String, newName:String, depth:Number):MovieClip
//idName - the linkage identifier of the movie clip in the library
//newName - the name for the movie clip once it is attached to the stage, this is the instance name of the movie clip
//depth - the depth to attach the movie clip at
```
