I have a flash file which loads an external SWF (call it external.swf) into the main timeline, on level 10. In this case, using _root or _parent to call the symbols on the main timeline will not work, since _root or _parent would refer to items on _level10.

The main timeline also contains a movie clip called “swapColors_mc” with two frames called “red” and green”.

To control the color change of swapColors_mc by clicking a button in external.swf once it is loaded, open “external.fla” (the original flash file from which external.swf is created) and add this actionscrip to the button:


on (release) {
_level0.swapColors_mc.gotoAndPlay("green");
}
