ActionScript 3.0 :: Counter Variable - Round To Number From Range

I'm trying to syncronize an audio and some text by highlighting it. In the main movie I have counter variable which calls charCounter3.as and timeVars variable which calls timeSettings.as I have onEnterFrame function that highlights the text while sound is playing.

My code is:
function onEnterFrame(e:Event):void {
pos=soundChannel.position;
var minutes:uint=Math.floor(soundChannel.position/1000/60);
var seconds:uint=Math.floor(soundChannel.position/1000)%60;
debug_txt.text='position: '+pos;
[Code] .....

Highlighted text needs to be updated on audio forwards and backwards. I think onEnterFrame isn't being able to catch the timeArr values.
