(Flash 8) Replacing color fill in movieclips?

Hello all.

I have another small question regarding dynamic color in movieclips. Essentially, I am looking for a way to find a color within a movieclip (like #999999 in the below sample) and replace that color with something else (like #ffd223). [COLOR=Red]But, I want the stroke around the circle to remain [/COLOR][COLOR=Red]untouched.[/COLOR]So, the script would only find a certain fill, and color only that area.
I tinkered with the *beginFill *method but couldn’t get it working. Any ideas would be much appreciated. =)-- james
