Undefined property keyCode! Please help! Can't find what's wrong!

[MrButlerC]

So I'm doing this coding for a college project and I've been repeating retyping the code for 3 times and the same problems still appear!

Here's the code

function keyDownHandler(Event:KeyboardEvent):void

  {

  if(event.keyCode == 38)

  {

  SpeedVert -= .2;

  avatar_mc.gotoAndStop("up")

  }

  else if(event.keyCode == 37)

  {

  SpeedHor -= 1;

  avatar_mc.gotoAndStop("left")

  }

  else if(event.keyCode == 39)

  {

  SpeedHor += 1;

  avatar_mc.gotoAndStop("right")

  }

The Problem

1119: Access of possibly undefined property keyCode through a reference with a static type flash.events:MouseEvent

1119: Access of possibly undefined property keyCode through a reference with a static type flash.events:MouseEvent

1119: Access of possibly undefined property keyCode through a reference with a static type flash.events:MouseEvent

The problem is the keyCode! I can't figure aout what's wrong!

Thank for anyone who's helping!

In your function definition line you use "Event" (wrong) while the code within the function uses "event" (better).  Fix that for starters.  Also, because the messages all have "MouseEvent" identified in them, I have to wonder if the event listener you have assigned is not specified as a KeyboardEvent listener

When I change the Event to event it works! Thanks! and It appear a new problem, mind if I copy all of the code? It have 120 line codes..

the problem is

1084 Syntax error: expecting right paren before rightbrace

[Ned Murphy]

You're welcome.  You can show all that code if you like, but if it is a problem with a misplaced or missing parenthesis you might want to spend some time trying to find it yourself before giving in and asking someone else to.

Okay! It works now!

I'm making a landing game? but it seems it can't land it's just passing the landing area..

Full Code:

Which section of the code you show is relevant to the landing that is giving you a problem? 

[MrButlerC]

Nevermind I just got it!

Thanks for your help!
