Frame control on mouseover/click (urgent)

I’ve been brought in at the last minute to finish off someone elses code on a project and having some trouble getting something to work…
The following is from an AS3 applet which slides 4 panels, populated with photos & links from the CMS. I need the timer to pause & reset when I rollover the tab that is open at the time. I onlny have a couplle hours to figure this out!
Thanks for your help,
J

 
var tempo:Timer = new Timer(7000);
tempo.addEventListener(TimerEvent.TIMER, nextTAB);
function nextTAB(evt:TimerEvent):void
{
 switch (superID)
 {
  case 1 :
   moveTAB2();
   break;
  case 2 :
   moveTAB3();
   break;
  case 3 :
   moveTAB4();
   break;
  case 4 :
   moveTAB2();
   break;
 }
}
function resetLoopTAB()
{
 tempo.stop();
 timer_preload.gotoAndPlay(1);
 tempo.start();
}
tempo.start();
