Placing a stop to Tweened Buttons

Question

Hi Guys,
I realize I might have done this the hard  way, but bear with me as I am brand new to flash and need to get a  simple presentation done for my boss by the end of the afternoon.
I  have created set of dials/meters with moving arms that change as  buttons are pressed.  The arms move based on a "Classic Tween" set-up I  created.  I then applied my buttons to the flash document and then coded  in some "gotoAndPlay" on an actions layer to get the arms on the dials  to move when I click on the buttons.  My problem is that since I have 3  buttons (High, Medium & Low) and the tweens follow one frame right  after another (0, 41,78) there is no stop.  When I click on Low it plays  the low tween, the medium one, and the high tween.  When I click on the  medium it plays both the Medium and then the High.  The High button  obviously only plays itself.  I don't know how to insert a stop between  these buttons.  Can you guys help me?  I have pasted my simple code  below os you can see it:
stop();
low_btn.addEventListener(MouseEvent.CLICK, onLow);
function onLow (Event:MouseEvent):void
     gotoAndPlay(0)
med_btn.addEventListener(MouseEvent.CLICK, onMed);
function onMed (Event:MouseEvent):void
     gotoAndPlay(41)
high_btn.addEventListener(MouseEvent.CLICK, onHigh);
function onHigh (Event:MouseEvent):void
     gotoAndPlay(75)
Please, please, please help me.
Thank you so much.

Answer 1

This answer seems intuitive, but I am wondering how to add that stop?
Do I add the stop to my Actions Layer or on the layer that has the actual moving arm?
Also, how to apply it to the specific frame? Just put the frame number in the paranthesis?
Thanks
