Mini Platformer movement problem

Hi I just finished the Mini platformer tutorial on TDN but when I test ran it my char. just stayed in the same spot I put him in the level editor suspended over the first platform. Now I double checked my code and its exactly like the one in the tut. And even though I used my own sprites I named everything exactly as if I used the ninja sprite. Im currently using the newest version of TGB if that would make a difference on this code. And if it doesn't and the code posted bellow doesn't have anything wrong with it what would be the thing to look for in the Level builder that would cause this. And I made sure to put the
exec("./playerClass.cs"); in the game.cs.

player.cs code:

function playerClass::onLevelLoaded(%this, %scenegraph)
{
$player = %this;

moveMap.bindCmd(keyboard, "left", "playerLeft();", "playerLeftStop();");
moveMap.bindCmd(keyboard, "right", "playerRight();", "playerRightStop();");
moveMap.bindCmd(keyboard, "space", "playerJump();", "");

%this.enableUpdateCallback();
}
function playerLeft()
{
$player.moveLeft = true;
}

function playerLeftStop()
{
$player.moveLeft = false;
}

function playerRight()
{
$player.moveRight = true;
}

function playerRightStop()
{
$player.moveRight = false;
}

function playerJump()
{
if(!$player.airborne)
{
$player.setLinearVelocityY(-150);
$player.airborne = true;
}
}
function playerClass::updateHorizontal(%this)
{
if (%this.moveLeft == %this.moveRight)
{
%this.setLinearVelocityX(0);
return;
}

if (%this.moveLeft)
{
if (!%this.againstLeftWall)
{
%this.againstRightWall = false;
%this.setLinearVelocityX(-30);
}
}

if (%this.moveRight)
{
if (!%this.againstRightWall)
{
%this.againstLeftWall = false;
%this.setLinearVelocityX(30);
}
}
}
