It seems that "sound" is a reserved keyword in flash. I made a sound movie clip and gave it the variable name "sound". BUT the object would never work when I called methods on it (EX : setVolume())....then I decided to rename the variable, and voila! the methods worked perfectly. Has anyone else ever experienced this problem?
"The Sound object allows you to set and control sounds in a particular movie clip instance, or for the global Timeline, if you do not specify a target when creating a new sound object. You must use the constructor new Sound to create an instance of the Sound object before calling the methods of the Sound object.
The Sound object is only supported for the Flash 5 Player. "
