Web Service Operation returns null values

Question

I got a Flash program that uses a Web Service.  I linked the actionscript to the Flex Files to get my connection to work.  I got it to work fine, but the problem is with sending it parameters.  This only works on functions without parameters.  But when I try to pass parameters, it returns null.  I also tried using the argruments function, but that caused it to return error.  What do I do to make it work?  Here is my code below:
stop();
import flash.display.MovieClip;
import flash.events.MouseEvent;
import mx.rpc.soap.*;
import mx.rpc.events.*;
import mx.rpc.AbstractOperation;
import flash.events.Event;
import flash.utils.Timer;
var webService:WebService = new WebService();
webService.wsdl = "http://www.askent.com/ttcs.asmx?WSDL";
webService.loadWSDL();
var serviceOperation:AbstractOperation;
/*var loginTimer: Timer = new Timer(1000, 1);
loginTimer.start();*/
var loginOperation: AbstractOperation;
var nickname:String;
var token:String = "token";
var gameName:String = "CRAZ";
//loginTimer.addEventListener(TimerEvent.TIMER, SetupWebService);
signin_btn.addEventListener(MouseEvent.CLICK, login);
/*function SetupWebService(event: TimerEvent):void{
          webService.loadWSDL("http://www.askent.com/ttcs.asmx?WSDL");
          webService.addEventListener(LoadEvent.LOAD, BuildServiceRequest);
function BuildServiceRequest(evt:LoadEvent){
          /*loginOperation = webService.getOperation("GuestLogin");
          loginOperation.send(nickname, token, gameName);
          //nickname = name_input.text;
          loginOperation.addEventListener(FaultEvent.FAULT, DisplayError);
          loginOperation.addEventListener(ResultEvent.RESULT, DisplayResult);*/
          trace("connected");
function login(event: MouseEvent): void{
          loginOperation = webService.getOperation("GuestLogin");
          //nickname = name_input.text;
          loginOperation.addEventListener(FaultEvent.FAULT, DisplayError);
          loginOperation.addEventListener(ResultEvent.RESULT, DisplayResult);
          //loginOperation({Nickname: nickname, Token: token, GameName: gameName});
          //loginOperation.arguments = {nickname: "GGG", Token: "token", GameName: "gameName"};
          loginOperation.send([nickname, token, gameName]);
function DisplayError(evt:FaultEvent){
                              trace("error");
function DisplayResult(evt:ResultEvent)
          var wsdlResponse:String = evt.result as String;
          trace(wsdlResponse);
function sendLogin(nickname: String, token: String, gameName: String): String{
          return nickname + token + gameName;

Shay,
The link worked. I generated Java Web Service from my WSDL, and tested using the HTTP analyzer
But for get Operation method on the WSDL, I could not see anything in the response object, but the same operation i could see the output in soapUIPro.
Can you give me some more guildelines to debug...
Thanks,
Sri
