[help please] Key quest, set Action id. [needed]

[RealSoft2]

Hi there, how the d--n I fix this thing..

function onUse(cid, item, frompos, item2, topos)
if item.uid == 15078 then
  queststatus = getPlayerStorageValue(cid,15078)
  if queststatus == -1 or queststatus == 0 then
   doPlayerSendTextMessage(cid,22,"You have found a bunch of weird stuffs.")
   item_uid = doPlayerAddItem(cid,2524,1)
   setPlayerStorageValue(cid,15078,1)

  else
   doPlayerSendTextMessage(cid,22,"it\'s empty.")
  end
else
  return 0
end
return 1
end

This is a typical quest script I use, but I want to know 2 things about this..

First: how do I add an action id to the loot item?

Second: how do I set so this item is looted in a bag? (you loot a bag with this item in)
