How to pass the MainMenu[id] value through an array?

Hi!

I need automatically make tree of MainMenu, using ID of menu items.

====


function FindMenu()

{
var arr = new Array();

var MainMenu = Sys["Process"]("myprocess")["VCLObject"]("fmMain")["MainMenu"];



//Makes list of all MainMenu items id.


  for (var i = 0; i < Count; i++)

      

      {

        var Item = MainMenu["Items"](i);

        arr = Item["id"];

        Log.Message("" + arr, "");

      }




//Makes list of all MainMenu SubMenu items 


  for (var i = 0; i < Count; i++)

      {

        var id = arr;

        var SubMenuCnt = MainMenu["Items"](id)["SubMenu"]["Count"];

        Log.Message("" +SubMenuCnt, "");

      }

}
===

error "Object needed" appears at this string:

var SubMenuCnt = MainMenu["Items"](id)["SubMenu"]["Count"];



I know that this string work fine:

var SubMenuCnt = MainMenu["Items"]("[1]")["SubMenu"]["Count"];

but i dont know how make from value in arr correct [id] for this string.



Please help.
