How can I write superscript font to input text in Flash 8 .

The problem is the equation must be enter in normal text.

( to enter 4 y 3 key sequence use are 4 y 3 the character must be formatted as it is being type )


eg .if we wrote (4 y 3 +2 y 2 - y )to input text ...

it must change formatted to
4y3 +2y2 -y

{4"y power 3"('3' is superscript font )+2"y power 2"('2'is superscript font)- y}.

I wrote this program....but it can't change superscript font .

var keyListener:Object = new Object();
var str:String = " ";
var userInput:String = "";
keyListener.onKeyUp = function() {
    var output:String="";
    var aText:Array = equation.text.split("");
 
    var isFollowLetter:Boolean;
    for(var i:Number=0; i<aText.length;i++){
        switch(aText[i]){
            case "0":
            case "1":
            case "2":
            case "3":
            case "4":
            case "5":
            case "6":
            case "7":
            case "8":
            case "9": {
                    if(isFollowLetter)
                        output+="<font face='GG Superscript'>"+aText[i]+"</font>";// what is wrong ?I already embed GG superscript in flash
 
                    else
                        output+= aText[i];
                    isFollowLetter = false;
                    break;
                  }
            case "+":
            case "-":
            case "*":
            case "/":
                output+= aText[i];
                isFollowLetter = false;
                break;
            default : {
                output+= aText[i];
                isFollowLetter = true;
                }      
        }
    }
    trace(output);
    //trace(aText);
    equation.htmlText = output;
};
 
   Key.addListener(keyListener);

Thanks for your time !!
