More Movement Problems

Hey everyone, now that a couple of things worked for me, a lot more had to go wrong to balance it out. I'm in the fish tutorial 4.4, where it helps me clean up movement. I put in everything it says. Then when I run the game, my fish moves exactly the same, there is also an error in line 3 of my code, though I have no idea what it is. Here's a script sample.

function Playerfish::onLevelLoaded(%this, %scenegraph)

function PlayerFish::updateMovement(%this)
{
if(%this.moveLeft)
{
$FishPlayer.setFlipX(false);
$FishPlayer.setLinearVelocityX( -$FishPlayer.hSpeed );
}

if(%this.moveRight)
{
$FishPlayer.setFlipX(true);
$FishPlayer.setLinearVelocityX( $FishPlayer.hSpeed );
}
if(%this.moveUp)
{
%this.setLinearVelocityY( -$FishPlayer.vSpeed );
}
if(%this.moveDown)
{
%this.setLinearVelocityY( $FishPlayer.vSpeed );
}
if(!%this.moveLeft && !%this.moveRight)
{
%this.setLinearVelocityX( 0 );
}
if(!%this.moveUp && !%this.moveDown)
{
%this.setLinearVelocityY( 0 );
}
}
{
$FishPlayer=%this;

moveMap.bindCmd(keyboard,"w","fishPlayerUp();","fishPlayerUpStop();");
moveMap.bindCmd(keyboard,"s","fishPlayerDown();","fishPlayerDownStop();");
moveMap.bindCmd(keyboard,"a","fishPlayerLeft();","fishPlayerLeftStop();");
moveMap.bindCmd(keyboard,"d","fishPlayerRight();","fishPlayerRightStop();");
moveMap.bindCmd(keyboard,"space","fishPlayerBoost();","fishPlayerBoostStop();");
}

function fishPlayerUp()
{
$FishPlayer.moveUp = true;
$FishPlayer.updateMovement();
}
function fishPlayerDown()
{
$FishPlayer.moveDown = true;
$FishPlayer.updateMovement();
}
function fishPlayerLeft()
{
$FishPlayer.moveLeft = true;
$FishPlayer.updateMovement();
}
function fishPlayerRight()
{
$FishPlayer.moveRight = true;
$FishPlayer.updateMovement();
}
function fishPlayerUpStop()
{
$FishPlayer.moveUp = false;
$FishPlayer.updateMovement();
}
function fishPlayerDownStop()
{
$FishPlayer.moveDown = false;
$FishPlayer.updateMovement();
} function fishPlayerLeftStop()
{
$FishPlayer.moveLeft = false;
$FishPlayer.updateMovement();
}
function fishPlayerRightStop()
{
$FishPlayer.moveRight = false;
$FishPlayer.updateMovement();
}

function fishPlayerBoost()
{
%flipX = $FishPlayer.getFlipX();
if(%flipX)
{
%hSpeed = $FishPlayer.hSpeed * 3;
} else
{
%hSpeed = -$FishPlayer.hSpeed * 3;
}
$FishPlayer.setLinearVelocityX(%hSpeed);
}

function fishPlayerBoostStop()
{
$FishPlayer.setLinearVelocityX(0);
}

Thanks, I'd appreciate any help.
