Quick class question

I have recently jumped into the world of custom class development. I have a quick question about what direction to take on this.

I have a custom class that basically will, onRollOver, cause a movie to fade in, and onRollOut, do the opposite. I have got that working correctly.

I have twenty five movie clips that need to function the same exact way. All of these mc’s are housed in one container_mc. They have the instance name of “mcBlip”.

How can I implement this class once and make everything instanced as “mcBlip” in the “container_mc” clip function?

Note: the movie structure is like this.

container_mc - holds twenty five clips named panel1, panel2, etc…

inside the panel1 mc’s is a two layer mc the top layer mc is “mcBlip” that I want to fade in/out

Any help on pointing me in the right direction would be greatly appreciated.
