Making a customized clock

Question

Hello  I'm building a customized clock at the moment. For seconds i'm using 12 movieclips with bars inside (fig1)
For every second a bar lights up. I can get the number of "group" to pick and the number of "bar" to light up but i can't actually make them light up because I'm not sure how to actually select the group of bars according to the time. My movieclips are called "group0", "group1" etc. and inside I made different states depending on how many bars light up (fig2)
fig1 fig2
Here's my code:
var now:Date;
var hour:Number;
var min:Number;
var sec:Number;
var group_access:Number;
var specificbar:Number;
addEventListener(Event.ENTER_FRAME, settime);
function settime (evt:Event) {
      //get time
      now = new Date();
      //check hours and set
      if (now.getHours() > 12) {
     hour = now.getHours() - 12;
      } else if (now.getHours()==0) {
       hour=12;
      } else {
       hour=now.getHours();
      //set min and sec
      min=now.getMinutes();
      sec=now.getSeconds();
addEventListener(Event.ENTER_FRAME, setSecs);
function setSecs (evt:Event) {
//Task: Light up a bar every second
group_access = (Math.floor ( (sec*2 )/10) ); // to selects the right group of bars eg. 33 seconds will be group 6
specificbar = sec-(group_access * 5); // to light up the right bar inside the group
// Need help with this part to work out how to access the moviclip according to the seconds on the clock
Really worried right now, please help and thank you

Answer 1

ok i've traced :
trace(group_access , specificbar);
result:
3  4
3  4
3  4
3  4
4  0
4  0
4  0
seems right =S
group no.3 and bar no. 4
then group 4
