Problem with volumeBar controlling more than one FLVPlayback

I have a movie with instances of FLVPlaybacks on different keyframes of the main timeline. I have dragged an instance of a volumeBar into my video controls clip and linked it, on each of these keyframes, to the various FLV’s with the line of code

my_FLVPlybk1.volumeBar = videocontrols.myVolumeBar;

however, when i play the movie and jump to each of these keyframes, an extra arrow appears on the slider, so by the time i have seen all four FLV’s, there are four arrows all around the same slider - which is obviously causing problems with controlling the volume.

I have tried using different instances of the volumeBar with different names, but the problem is not resolved.

can anyone help?

thanks on advance
