Animating changes in size on BONED symbols/movie clips

Hi guys,

I’m fairly new to Flash and have been learning how to use the bone tool, but I can’t figure out how to change the SIZE of a symbol that has been “boned”, AND get Flash to animate that change in size.

This is basically what I’ve been trying to do…

[]I have a stick figure and I’m animating his arm.
[
]The arm consists of 3 movie clips: Hand, forearm, upper arm.
[]The 3 movie clips have been boned together and are now on their own armature layer.
[
]I can change the size of one of the movie clips using the transform tool in a specific frame in the timeline, but Flash doesn’t JUST change the size of the movie clip in the specified frame, but changes it across all frames in the armature layer.

If anyone knows if this is possible or how to do it, any help would be appreciated. Even if you can just direct me to a tutorial or a guide somewhere.

I’ve done my best to be as clear as possible, but if any of this isn’t clear or you need more information, please let me know.

Thanks, guys.
