Function is undefined for no apparent reason - actionscript-3

Question

I have two event listeners calling two functions, the first checkKeyDown and then the second checkKeyUp.
package {
import flash.display.MovieClip;
import flash.events.MouseEvent;
import flash.events.KeyboardEvent;
import flash.events.Event;
import flash.ui.Keyboard;
public class Code extends MovieClip {
var charSpeed:int = 0;
var velocity:int = 0;
var gravity:Number = 1;
var Jump:Boolean = false;
public function startGame(){
stage.addEventListener(KeyboardEvent.KEY_DOWN, checkKeyDown);
stage.addEventListener(KeyboardEvent.KEY_UP, checkKeyUp);
}
public function Code() {
// constructor code
}
function checkKeyDown(evt:KeyboardEvent){
if (evt.keyCode == Keyboard.LEFT){
charSpeed -= 10;
}
if (evt.keyCode == Keyboard.RIGHT){
charSpeed += 10;
}
if (evt.keyCode == Keyboard.DOWN){
if(!Jump){
velocity -= 14;
Jump = true;
}
}
function checkKeyUp(e:KeyboardEvent){
if (e.keyCode == Keyboard.LEFT){
charSpeed = 0;
}
if (e.keyCode == Keyboard.RIGHT){
charSpeed = 0;
}
}
When I first typed the code, I did the checkKeyDown function first, and when I ran it, it worked fine (without the checkKeyUp event listener of course). After this, i added the event listener and checkKeyUp function to the code, but I got an error saying "1120: Access of undefined property checkKeyUp." I have no idea why this has come up, as the checkKeyDown function works fine. If I could get some help on why I am getting this error, that would be great.

You forget a brace (char '}') at the end of checkKeyDown function.
