Dynamically read data from a txt document

Question

I try to dynamically read data from a txt document
in swf
stop ();
var pafh=this;
import flash.events.*;
var Araray_id:Array =new Array();
var v_length:Number;
var myTextLoader:URLLoader = new URLLoader();
myTextLoader.dataFormat=URLLoaderDataFormat.VARIABLES;
myTextLoader.addEventListener(Event.COMPLETE, onLoaded);
function onLoaded(e:Event):void {
        Araray_id = e.target.data.araray_id.split(",");
        trace("Araray_id: "+Araray_id);
        v_length=Araray_id.length;
        trace("v_length: "+v_length);
        for (var i:Number=0;i<v_length;i++){
            pafh["Id_"+i]=new Array();
            trace("pafh[Id_+i]: "+pafh["Id_"+i]);
            var v_help:Object="id_"+i;
            trace("v_help: "+v_help);
            //pafh["Id_"+i]= e.target.data.v_help.split(",");????? Here stops the script
            //pafh["Id_"+i]= e.target.data.(v_help).split(",");????Here stops the script
            //pafh["Id_"+i]= e.target.data.[v_help].split(","); ????Here stops the script
        play();
myTextLoader.load(new URLRequest("myText1.txt"));
in text
araray_id=aa,bb,cc,dd,ee,ff
&id_0=aa1,aa2,aa3,aa4
&id_1=bb1,bb2,bb3,bb4,bb5
&id_2=cc1,cc2,cc3
&id_3=dd1,dd2,dd3,dd4,dd5,dd6
&id_4=ee1,ee2
&id_5=ff1,ff2
output
Araray_id: aa,bb,cc,dd,ee,ff
v_length: 6
pafh[Id_+i]:
v_help: id_0
TypeError: Error #1010: A term is undefined and has no properties.

Can you help me with this problem

More suggestions.
1. If you align naming conventions between data and your application - reading data could be practically a one-liner.
If you write pafh["id_" + i] (with small case i) instead of pafh["Id_" + i] (with capital case I) the function can be just:
function onLoaded(e:Event):void
          for (var prop:String in e.target.data)
                    pafh[prop] = e.target.data[prop].split(",");
          play();
2. If changing conventions is not feasible, here is another thing you can do:
function onLoaded(e:Event):void
          for (var prop:String in e.target.data)
                    pafh[prop.replace(/^\w/, String(prop.match(/^\w/)).toUpperCase())] = e.target.data[prop].split(",");
          play();
