Problem adding "attributes" to the Player class. NEED HELP.

Basically, I'm attempting to add "attributes" to the player class, (Such as strength and whatnot). And I'm having trouble exposing the variables to script.

This is what I have so far... everything compiles fine, but I'm not sure/able to access "updateFortitude()" from script. Right now, I'm trying to call it from within GameConnection::onConnect, then using the command

%client.updateFortitude(10)

But I get the error "scripts/server/gameCore.cs (281): Unknown command updateFortitude.

bool Player::updateFortitude(F32 value)
{
	fortitude += value;
	F32 oldF = fortitude;
	if(fortitude < 10)
		return false;

	Con::printf("Added 10 to fortitude!nFortitude was: %d and is now: %d", oldF, fortitude);

	return true;
}

DefineEngineMethod( Player, updateFortitude, bool, ( S32 arg1 ),,"empty for now")
{
   return object->updateFortitude(arg1);
}
