Professional :: Sending Two Strings At Same Time

I am programing a flash page but writing function to send two stings at the same time? In my case, I would send backwardH and backwardLI have has tested all three options, but there is no error but either backwardH or backwardL movieclipet gets affected, not both at the same time though I would like both to be influenced at the same time. For example if I click button_1 then movieclip_1 and movieclip_2 would play. And if I click button_2 then just movieclip_1 would play.

//Option1
family.margeAS3.addEventListener(MouseEvent.CLICK, fl_MouseClickHandler_3);
function fl_MouseClickHandler_3(event:MouseEvent):void{
direct = "backwardH", "backwardL" ;margePa.play();}

//Option2
family.margeAS3.addEventListener(MouseEvent.CLICK, fl_MouseClickHandler_3);
function fl_MouseClickHandler_3(event:MouseEvent):void{
direct = "backwardH" + "backwardL";
margePa.play();}

//Option3
family.margeAS3.addEventListener(MouseEvent.CLICK, fl_MouseClickHandler_3);
function fl_MouseClickHandler_3(event:MouseEvent):void{direct = "backwardH";
direct = "backwardL" ;margePa.play();}
