score and lives -games actionscript 3.0

Hi, PLEASE HELP ME.....

do you think my coding is OK?

this score cannot function on another timeline *label*...

var total:int = 0;

myScore.text = total.toString();

blink_btn.addEventListener(MouseEvent.CLICK,fl_MouseClickHandler);

function fl_MouseClickHandler(event:MouseEvent):void

{

  total = total + 1;

  myScore.text = total.toString();

}

ignore_btn.addEventListener(MouseEvent.CLICK,fl_MouseClickHandler_2);

function fl_MouseClickHandler_2(event:MouseEvent):void

{

  total = total - 1;

  myScore.text = total.toString();

}

use a variable to track the score, a variable for the amount to adjust the score for a correct answer and a third variable for the amount to adjust the score for an incorrect answer.  eg,

var score:int = 0;

var correctInc:int = 10;

var incorrectInc:int = -5;

you can then use something like:

function scoreF(b:Boolean):void{

if(b){

score+=correctInc;

} else {

score+=incorrectInc;

}
