Help with rotating circular menu

Question

Hi there. With help from a few tutorials, I've made a menu with 5 buttons that rotate around a central Clip. So far so good.
Except I need to add a lightning that will point toward the center whenever a button is activated. Much like picture below:
Everything I've tried so far has produced unexpected results
So I would really appreciate any suggestions as to how I might fix my code (AS2) and get the lightning to position itself where it must be. Thanks!
var rotX:Number = 290;
var rotY:Number = 140;
var Centre:Number = Stage.height/2;
var vitesse:Number = 0.1;
var sceneW:Number =Stage.width;
var sceneH:Number = Stage.height;
var nbI:Number=5;
var angle:Number=1;
var i:Number;
var lightning:MovieClip = this.attachMovie("lightning", "lightning", 1000);
lightning._alpha = 0;
var videostopped:Boolean = false;
for(i=0;i<nbI;i++)
   var button:MovieClip = this.attachMovie('Icone'+i,'Ic'+i,i);
   button.onRelease= onRelease;
   button.onRollOut = onRollOut;
   button.onRollOver = onRollOver;
   button._y = sceneH /2;
//_____________________test
function onRollOver():Void {
        //I want to add a "lightning" movieClip between the center and the button that is rolled over     
   lightning._alpha = 100;
   videostopped = true;
function onRollOut():Void {
        //then remove it.
   lightning._alpha = 0;
   videostopped = false;
onEnterFrame=function(){
     if (!videostopped) {
      if (angle > (2*Math.PI))
           angle = 0;
      }else{               
           for(i=0; i<nbI; i++){
               //_____________________angle on x axis
               this['Ic'+i]._x=rotX*Math.cos(angle+2*Math.PI*i/nbI)+sceneW/2;
               //_____________________angle on y axis
               this['Ic'+i]._y=rotY*Math.sin(angle+2*Math.PI*i/nbI)+sceneH/2;
               //_____________________Speed
                    angle=angle+(sceneW/180)/sceneH*vitesse;

I'll probably have to leave you to minds greater than mine for a solution to this.  To have things arranged with long rectangles and a flattened oval shaped path around the center as you show complicates matters in terms of how the _x/_y properties need to vary in order to not be hitting the inner or outer buttons.
If it were mine to solve I would probably bend towards making the buttons circular shapes that follow a truly circular path around the center.  Then I would only have to manage the _rotation value of the lightning bolt which would have its registration at the center of the central button--essentially going around like the hand of a clock.
