GettingStarted.pdf tutorial problem

I think the GettingStarted.pdf tutorial is bad at the scripting part, after i entered these lines individually, i tested if everything worked and they did but... in game when moving the mouse up/down or left/right the camera is still the screen was standing still! i need to complete this tutorial, please check the code below and tell me where it's bad.


these are the script i added to "logoitem.cs"

function TorqueLogoItem::onCollision(%this, %obj, %col)
{
if(%col.getClassName() $= "Player")
{
%client = %col.client;
%client.score++;
commandToClient(%client, 'SetScoreCounter', %client.score);
%obj.delete();
%logoCount = logos.getCount();
if(%logoCount > 0)
return;
// otherwise display victory screen
commandToClient(%client, 'ShowVictory', %client.score);
}
}


also i added the below to a new file named "clientGame.cs"

function clientCmdSetScoreCounter(%score)
{
ScoreCounter.setText("Score:" SPC %score);
}
function clientCmdShowVictory(%score)
{
MessageBoxYesNo("You Win!",
"Would you like to restart the game ?",
"loadMyMission();",
"quit();");
}


and this line to "main.cs" under "Client scripts" as stated in the tutorial

exec("./client/clientGame.cs");
