Lua Help with lever script

[Amare Aeternam]

Well, I've been working on a script that teleports a player only if they don't have certain items on them. (stops people from stealing game pieces) I'm not sure whats wrong so some help would be great

local baditems = { 
	(2638), --All the items you dont want through the door
	(2639),
	(2624),
	(2625),
	(2642),
	(2643),
	(2644),
	(2645),
	(2646),
	(2626),
	(2627),
	(2628),
	(2629),
	(2630),
	(2631)
}
local maxitems = (#baditems)
local currentitem = 1; --No Touchey
local turnbackdestination = {x=1189, y=1077, z=8} --Location where the player is teleported if he/she has a bad item
local destination = {x=1189, y=1067, z=8} -- Location to continue
local warningmessage = "Put back the game pieces :(" --Message sent to player when teleported
local baditem = 0

function onUse(cid, item, fromPosition, itemEx, toPosition)
	while (currentitem <= maxitems)
		if((getPlayerItemCount(cid, baditems[currentitem])) > 0) then
			doTeleportThing(cid,turnbackdestination)
			doSendPlayerTextMessage(cid, MESSAGE_INFO_DESCR, warningmessage)
			return TRUE
		end
		currentitem = currentitem + 1
	end
	doTeleportThing(cid,destination)
end
