Lua What is the problem in this script? [ HELP PLZ ]

[viniciusturko]

The script :

function onStepIn(cid, item, position, fromPosition)
for i, creature in pairs(getSpectators({x = 1390, y = 1042, z = 7}, 1, 1, false)) do
if isPlayer(creature) then
doTeleportThing(cid, {x = getCreaturePosition(cid).x, y = getCreaturePosition(cid).y + 1, z = getCreaturePosition(cid).z})
doSendMagicEffect(getCreaturePosition(cid), 2)
doPlayerSendTextMessage(cid, 19, "You cannot enter. There someone doing the quest now. Wait a minute.")
return 1
elseif isMonster(creature) then
doRemoveCreature(creature)
end
end
return true
end

The error :

Where is the error?

 

[Darkhaos]

The problem is "bad argument to #1 to 'pairs' (table expected, got nil)"

!

function onStepIn(cid, item, position, fromPosition)

	local list = getSpectators({x = 1390, y = 1042, z = 7}, 1, 1, false) or {}
	if #list > 0 then
		for _, creature in pairs(list) do
			if isPlayer(creature) then
				doTeleportThing(cid, {x = getCreaturePosition(cid).x, y = getCreaturePosition(cid).y + 1, z = getCreaturePosition(cid).z})
				doSendMagicEffect(getCreaturePosition(cid), 2)
				doPlayerSendTextMessage(cid, 19, "You cannot enter. There someone doing the quest now. Wait a minute.")
				return true
			elseif isMonster(creature) then
				doRemoveCreature(creature)
			end
		end
	end
	return true
end

function onStepIn(cid, item, pos, fromPos)
	if isPlayer(cid) then
		local t = {}
		for _, v in ipairs(getSpectators({x=1390, y=1042, z=7}, 1, 1) or {}) do
			if isPlayer(v) then
				pos.y = pos.y + 1
				doTeleportThing(cid, pos)
				doSendMagicEffect(pos, CONST_ME_POFF)
				doPlayerSendTextMessage(cid, MESSAGE_EVENT_ORANGE, 'You cannot enter. There\'s someone doing the quest now. Wait a minute.')
				return
			elseif isMonster(v) then
				table.insert(t, v)
			end
		end
		for i = 1, #t do
			doRemoveCreature(t[i])
		end
	end
end
