Firing multiple Bullets

Question

Hi,  I have written the code below which restricts the number of bullets fired, but each bullet fired travels at a different speed to the last and
when another bullet is fired the previous one disappears from the screen. Please can anyone give any guidance ?
import flash.display.MovieClip;
import flash.events.KeyboardEvent;
import flash.events.Event;
import flashx.textLayout.formats.BackgroundColor;
var speed:Number;
speed = 10;
var shootLimiter:Number=0;
var backgrou:MovieClip = new Background();
var bullet:MovieClip = new Bullet();
addEventListener(Event.ENTER_FRAME,backgroundmove);
backgrou.x =0;
backgrou.y = 45;
addChild(backgrou);
var ship:MovieClip = new Ship();
ship.x = 100;
ship.y =200;
addChild(ship);
function backgroundmove(e:Event):void
backgrou.x -= 1;
shootLimiter++;
if(backgrou.x < -2110)
backgrou.x = 0;
stage.addEventListener(KeyboardEvent.KEY_DOWN,KeyDown);
function KeyDown(event:KeyboardEvent):void
if((event.keyCode == 32) &&(shootLimiter>16))
AddBullet();
if(event.keyCode == 37){  //checks if left arrowkey is released.
ship.x -=5;
shootLimiter++;
if(event.keyCode == 39){  //checks if right arrowkey is released.
ship.x +=5;
shootLimiter++;
if(event.keyCode == 38){  //checks if up arrowkey is released.
ship.y -= 5;
shootLimiter++;
if(event.keyCode == 40){  //checks if down arrowkey is released.
ship.y+= 5;
shootLimiter++;
function AddBullet()
bullet.x = ship.x +100;
bullet.y = ship.y + 30;
addChild(bullet);
shootLimiter=0;
addEventListener(Event.ENTER_FRAME,movebullet);
function movebullet(e:Event):void
     bullet.x += speed;
     if(bullet.x > 800)
         if(contains(bullet)){
           removeChild(bullet);
          removeEventListener(Event.ENTER_FRAME,movebullet);

You only have one bullet:
var bullet:MovieClip = new Bullet();
adding child on it does not make a new one. You need something like:
addChild(new Bullet());
to make multiple bullets.
In addition nested functions are a poor choice, you should remove moveBullet from inside of addBullet. The you probably want to make a bullet class that is linked to your library bullet clip - then bullets can move and remove themselves.
