AS3 Animation won't play - actionscript-3

Question

Fairly new to programming, slowly getting the hang of it. I've come across a problem I've spend hours on trying to fix but can't seem to get the result I'm looking for. I have made running animation for my character. He runs left, up, down, right, upRight, downRight BUT upLeft and downLeft the animations do not play. He moves in the correct direction but the animations that are being played are upRight and downRight. I've changed the animations for upLeft and downLeft to my "idle" animation and it works. I'm unsure as to why this is happening if all the other animations work correctly.
Here is my code for my player animation. Any help or advice would be great. Thanks in advance
package {
import flash.display.MovieClip;
import flash.display.*;
import flash.events.*;
public class PlayableCharacter extends Character
{
private var dx:int;
private var dy:int;
var ready:Boolean;
public function PlayableCharacter(x:int=0, y:int=0, dx:int = 3, dy:int = 3)
{
// constructor code
this.x = x;
this.y = y;
this.dx = dx;
this.dy = dy;
ready = true;
gotoAndStop("Idle");
addEventListener(Event.ENTER_FRAME,onEnter);
addEventListener(Event.ADDED_TO_STAGE, onStage);
}
private function onEnter(e:Event)
{
//doing animation stuff
if(!leftPressed && !rightPressed && !downPressed && !upPressed)
{
gotoAndStop("Idle");
}
//Go Left
if(leftPressed && !upPressed && !downPressed && !rightPressed)
{
//do something left
goDown(-dx)
gotoAndStop("Run");
}
//Go Right
if(rightPressed && !upPressed && !downPressed && !leftPressed)
{
//do something right
goDown(dx)
gotoAndStop("Run");
}
//Go Up
if(upPressed && !leftPressed && !rightPressed && !downPressed)
{
goUp(-dy)
gotoAndStop("RunUp");
}
//Go Down
if(downPressed && !upPressed && !rightPressed && !leftPressed)
{
goUp(dy)
gotoAndStop("RunDown");
}
//Go UpRight
if(rightPressed && upPressed && !leftPressed && !downPressed)
{
goDown(dx)

}

}
// Go Downleft

{

}
if (x > stage.stageWidth)
x = stage.stageWidth;
else if (x < 0)
x = 0;
if (y > stage.stageHeight)
y = stage.stageHeight;
else if (y < 0)
y = 0;
}
public function onStage(e:Event)
{
}
public function goUp(dy:int=0)
{
y += dy;
if(scaleY > 0 && dy < 0)
{
scaleY *= 1;
}
else if(scaleY < 0 && dy > 0)
{
scaleY *= -1;
}
}
public function goDown(dx:int =0)
{
x += dx;
if(scaleX > 0 && dx < 0)
{
scaleX *= -1;
}
else if(scaleX< 0 && dx > 0)
{
scaleX *= -1;
}
}
}
}

At first glance I dont see anything wrong with your code. I always woud advise against using labels for frames but using their numbers instead.
The names of functions "goUp" and "goDown" are hinting in a wrong direction, I'd change them to "goVertical" and "goHorizontal". How are the leftPressed, rightPressed, ... variables set? Have you tried putting a trace inside each "if" to see if the problem is that the wrong if-block is executed or the animation is addressed wrongly? Have you double-checked the names of the frames and maybe tried it using their respective numbers?
