Using keyboardevent (newbie)

Question

Hi all,
In my file, I have an introduction playing over and over.  When someone hits the "K" button, I need the file to immediately go to and play a frame labeled "waterdepth".  What am I missing below?  I keep getting an error saying that "keyboard event cannot be loaded."
Help!
import flash.events.KeyboardEvent;
stage.addEventListener(KeyboardEvent.KEY_DOWN, waterdepth);
function waterdepth(e:KeyboardEvent):void {
    if(event.keyCode == 75) {
        gotoandPlay("waterdepth");

Answer 1

don't you see an error???
use:
import flash.events.KeyboardEvent;
stage.addEventListener(KeyboardEvent.KEY_DOWN, waterdepth);
function waterdepth(e:KeyboardEvent):void {
    if(e.keyCode == 75) {
        gotoandPlay("waterdepth");
