Play/Pause toggle used for multiple movieclips

programming flash

I am setting up a module that has about 10 movieclips, all on the stage on one layer. I have a play/pause toggle button and next button that I want to use as the media player for all the movieclips and just make the movieclips visible or not.
Does anyone have an idea of how I phrase a conditional statement to have subsequent movieclips play when the “next” button and then “play” are selected?
Here’s the code for the toggle with 2 movieclips in there. I appreciate any ideas.

var playing:Boolean=false;
toggle_mc.sto_btn.visible=false;
oveSe_mc.visible=true;
geZo_mc.visible=false;

toggle_mc.addEventListener(MouseEvent.MOUSE_UP,toPlay);
function toPlay(event:MouseEvent):void{
if (toggle_mc.pla_btn.visible == true){
oveSe_mc.stop();
toggle_mc.pla_btn.visible=false;
toggle_mc.sto_btn.visible=true;
playing=true;
}else {
oveSe_mc.play();
toggle_mc.pla_btn.visible=true;
toggle_mc.sto_btn.visible=false;
playing=false;
}
}
