Help with loot description.

if con.player and con.score ~= 0 then
                local lootMessage = ("The following items dropped by %s are available in your reward chest: %s"):format(creature:getName(), reward:getContentDescription())

                if stamina > 840 then
                    reward:getContentDescription(lootMessage)
                end
                con.player:sendTextMessage(MESSAGE_LOOT, lootMessage)
            elseif con.score ~= 0 then
                insertRewardItems(con.guid, timestamp, playerLoot)
            end

            os << "{" << item->getID() << "|" << item->getNameDescription() << "}";

os << item->getNameDescription();
