Autogiveitem - poly marble problem

[avertuss 48]

Hi. I have code:

LPITEM item = ITEM_MANAGER::instance().CreateItem(70104, 1, 0, true);
if (item)
{
	item->SetSocket(0, mobVnum);
	int iEmptyPos = ch->GetEmptyInventory(item->GetSize());

	if (iEmptyPos != -1)
	{
		ch->PointChange(POINT_GOLD, -price);
		item = ch->AutoGiveItem(item->GetVnum(), item->GetCount());
	}
	else
	{
		M2_DESTROY_ITEM(item);
		ch->ChatPacket(CHAT_TYPE_INFO, "No slots in inventory.");
		break;
	}
}
else
{
	ch->ChatPacket(CHAT_TYPE_INFO, "#%d item not exist by that vnum.", 70104);
	break;
}

that code is stacking marble but i can't use them beacuse they haven't socket. Any ideas?
