POmoc

Skinuo sam fantasy evolution i sad kad opljackam opstinu ili nesto i odem na trziste da prodam, mogu prodati npr. ogrlicu po 100 puta istu, jednom opljackam a prodam je koliko ja hocu puta....
Zna neko gdje je greska?
Eto taj kod ako je to to, ili nesto drugo treba

if(dialogid == 722)
    {
      if(response)

            if(listitem == 0)
			{
			    if(PlayerInfo <= 0)
			    {
			        SendClientMessage(playerid, COLOR_WHITE, "{FF0000} {FFFFFF}Nemate narukvicu.");
			        return 1;
			    }
				PlayerInfo --;
				new bonus = 500 + random(5000);
				GivePlayerMoney(playerid, 12000 + bonus);
			  	format(string, sizeof(string), "{0F629F}Isplata: {FFFFFF}Prodali ste narukvicu za %d $. ",10000 + bonus);
				SendClientMessage(playerid, 0x9A6735FF, string);
				//SBizzInfo += 1000;
				//ExtortionSBiz(75, 500);
 		 		}
      			if(listitem == 1)
				{
			    if(PlayerInfo <= 0)
			    {
			        SendClientMessage(playerid, COLOR_WHITE, "{FF0000} {FFFFFF}Nemate diplomu.");
