Link VolumeMute with VolumeBar

Hello all,
I’m using the volume mute and volumbar UI video components in flash. I’m trying to link both of them together, so that when you click on the mute button the volume bar goes down or if you bring the volume bar all the way down it changes the volume mute button and vice versa.

Any suggestions how to accomplish this? Ive been search google but no such luck.

Thanks,
Mark
