Stopped script lua

[79135 4]

Script good delete, but when GetContainerItemLink(b,s) == 'Hearthstone'  the script is stopped. Why?

Lua.LuaDoString("for b = 0,4,1 do for s = 1,GetContainerNumSlots(b),1 do name,_,_,_,_,_,_,_,_,_, itemSellPrice = GetItemInfo(GetContainerItemLink(b,s)) if name ~= 'Hearthstone' and itemSellPrice < 10 then PickupContainerItem(b,s); DeleteCursorItem(); end; end; end;");
