Saving a variable client-side (persistently)

[agribilos]

I need a little help.
Saving the players stats and updating them works fine using the functions from _stattracking.gsc (the non mysql version). Now i am trying to add a hud for displaying them. So because my coding experience is limited i tried modifying _hud_playerscore.gsc to test. I made a file called _myhud.gsc that contains :

init()
{
	
	level thread onPlayerConnect();


}

onPlayerConnect()
{
	for(;;)
	{
		level waittill("connecting", player);

		player thread onPlayerSpawned();
		player thread onJoinedTeam();
		player thread onJoinedSpectators();
		player thread onUpdatePlayerScoreHUD();
	}
}

onJoinedTeam()
{
	self endon("disconnect");
	
	for(;;)
	{
		self waittill("joined_team");
		self thread removePlayerHUD();
	}
}

onJoinedSpectators()
{
	self endon("disconnect");
	
	for(;;)
	{
		self waittill("joined_spectators");
		self thread removePlayerHUD();
	}
}

onPlayerSpawned()
{
	self endon("disconnect");
	
	for(;;)
	{
		self waittill("spawned_player");


		if(!isdefined(self.hud_deaths))
		{
		    self.hud_deaths = newClientHudElem(self);
		    self.hud_deaths.horzAlign = "left";
		    self.hud_deaths.vertAlign = "top";
		    self.hud_deaths.x = 36;
		    self.hud_deaths.y = 46;
		    self.hud_deaths.font = "default";
		    self.hud_deaths.fontscale = 2;
		    self.hud_deaths.archived = false;
		}


		self thread updatePlayerScoreHUD();
	}
}

onUpdatePlayerScoreHUD()
{
	for(;;)
	{
		self waittill("update_playerscore_hud");
		
		self thread updatePlayerScoreHUD();
	}
}

updatePlayerScoreHUD()
{
	if(isDefined(self.hud_deaths))
		deaths = self getstat("deaths");
		self.hud_deaths setValue(deaths);
}

removePlayerHUD()
{

	if(isDefined(self.hud_deaths))
		self.hud_deaths destroy();
}

I tried calling _myhud.gsc within _stattracking.gsc in the init function.

init()
{
    game["menu_clientcmd"] = "clientcmd";
    precacheMenu(game["menu_clientcmd"]);

    init_stattracking();
    init_ranks();
    thread waitforconnect();
    thread scanForBan();
	thread maps\mp\gametypes\_myhud::init();

}

When i try to run server i get this error:

******* script compile error *******
uninitialised variable 'deaths': (file 'maps/mp/gametypes/_myhud.gsc', line 86)
  self.hud_deaths setValue(deaths);
                           *
