Lua onDeath

[3l0]

Hello guys, i have nice problem... i made script which should remove monster corpse after 30 seconds of dead, but "corpse" value in script don't returns into function doRemoveItem in addEvent, i test it in 1 sec and 30 sec and not work.
Can someone help me ?

function onDeath(cid, corpse, deathList)
 
	if not(isMonster(cid)) then
		return TRUE
	end
	if(corpse.itemid > 0)then
		addEvent(doRemoveItem, 1000, corpse.uid, 1)
	end
	return true
end

btw. corpse.uid, corpse.itemid in function onDeath works correct, only in addEvent not working...

Thanks in advance.
