********EDITED:

spawnmoneyhuds()
{
    self endon("disconnect");
    self endon("joined_spectators");
    
    if(!isDefined(self.moneyhud))
    {
        self.moneyhud = newClientHudElem(self);
        self.moneyhud.x = 520; 
        self.moneyhud.y = 280; 
        self.moneyhud.alignX = "left";
        self.moneyhud.alignY = "middle";
        self.moneyhud.sort = 1; 
        self.moneyhud.alpha = 1;
        self.moneyhud.fontScale = 1.2;
        self.moneyhud.archived = true;
        self.moneyhud setText(game["hud_money"]);
    }

    if(!isDefined(self.moneyVALUEhud)) 
    {
        self.moneyVALUEhud = newClientHudElem(self);
        self.moneyVALUEhud.x = 600;
        self.moneyVALUEhud.y = 275;
    }

    while(1)
    {
        wait(1.1);
        self.moneyVALUEhud setvalue(self.money);
    }
}

Script compile error in line 622: wait(1.1);
