heres my code

function playerOneClass::onLevelLoaded(%this, %scenegraph)
{
$playerOne = %this;

// key bindings for player one
moveMap.bindCmd(keyboard, "w", "playerOneUp();", "playerOneUpStop();");
moveMap.bindCmd(keyboard, "s", "playerOneDown();", "playerOneDownStop();");
}

function playerTwoClass::onLevelLoaded(%this, %scenegraph)
{
$playerTwo = %this;

// key bindings for player two.
moveMap.bindCmd(keyboard, "UP", "playerTwoUp();", "playerTwoUpStop();");
moveMap.bindCmd(keyboard, "DOWN", "playerTwoDown();", "playerTwoDownStop();");
}

function ballClass::onLevelLoaded(%this, %scenegraph)
{
$ball = %this;
$player1 = 0;
$player2 = 0;

// start the ball off at a speed of 100 at a 45 degree angle
$ball.setLinearVelocityPolar(45, 100);
}

// player one movement
function playerOneUp()
{
$playerOne.moveUp = true;
}

function playerOneDown()
{
$playerOne.moveDown = true;
}

function playerOneUpStop()
{
$playerOne.moveUp = false;
}

function playerOneDownStop()
{
$playerOne.moveDown = false;
}

// player two movement
function playerTwoUp()
{
$playerTwo.moveUp = true;
}

function playerTwoDown()
{
$playerTwo.moveDown = true;
}

function playerTwoUpStop()
{
$playerTwo.moveUp = false;
}

function playerTwoDownStop()
{
$playerTwo.moveDown = false;
}

// check if the ball collides.
function ballClass::onCollision(%srcObj, %dstObj, %srcRef, %dstRef, %time, %normal, %contactCount, %contacts )
{
// this just makes sure the paddles stay put on their x axis
if(%dstObj.class $= "playerOneClass")
{
$playerOne.setPositionX(-96);
}

if(%dstObj.class $= "playerTwoClass")
{
$playerTwo.setPositionX(96);
}
}

// movment for player one
function playerOneClass::updateMovement(%this)
{
if (%this.moveUp)
{
%this.setLinearVelocityY(-100);
}

if (%this.moveDown)
{
%this.setLinearVelocityY(100);
}

if (!%this.moveUp && !%this.moveDown)
{
%this.setLinearVelocityY(0);
}

}

// movement for player two
function playerTwoClass::updateMovement(%this)
{
if (%this.moveUp)
{
%this.setLinearVelocityY(-100);
}

if (%this.moveDown)
{
%this.setLinearVelocityY(100);
}

if (!%this.moveUp && !%this.moveDown)
{
%this.setLinearVelocityY(0);
}

}



function ballClass::onWorldLimit(%this, %mode, %limit)
{

switch$ (%limit)
{

case "left":
$player1++;
echo ("p1scores") ;
case "right":
$player2++;
echo ("p2scores") ;


}


}

// update the scene
function t2dSceneGraph::onUpdateScene()
{
$playerOne.updateMovement();
$playerTwo.updateMovement();
}




the names of the score are guiplayera and guiplayer1 and guiplayerb and guiplayer2 for the other score

anyone work this out i'm stumped
