I'm using TFS 0.3.6


movements/scripts/tomb.lua

 local config = {
	[60063] = {{x=33073, y=32589, z=13}, {x=33079,y=32589,z=13}},
	[60064] = {x=33072,y=32589,z=13},
	[60065] = {{x=33098,y=32816,z=13}, {x=33093,y=32824,z=13}},
	[60066] = {x=33097,y=32815,z=13},
	[60067] = {{x=33135,y=32682,z=12}, {x=33130,y=32683,z=12}},
	[60068] = {x=33136,y=32683,z=12},
	[60069] = {{x=33161,y=32831,z=10}, {x=33156,y=32832,z=10}},
	[60070] = {x=33162,y=32832,z=10},
	[60071] = {{x=33233,y=32692,z=13}, {x=33234,y=32687,z=13}},
	[60072] = {x=33234,y=32693,z=13},
	[60073] = {{x=33240,y=32855,z=13}, {x=33246,y=32850,z=13}},
	[60074] = {x=33239,y=32856,z=13},
	[60075] = {{x=33276,y=32552,z=14}, {x=33271,y=32553,z=14}},
	[60076] = {x=33277,y=32553,z=14},
	[60077] = {{x=33293,y=32741,z=13}, {x=33299,y=32742,z=13}},
	[60078] = {x=33292,y=32742,z=13}
}
function onStepIn(cid, item, pos, fromPosition)
	if(config[item.uid]) then
		if(type(config[item.uid]) == "table") then
			local coin = getTileItemById(config[item.uid][1], 2159).uid
			if(coin > 0) then
				doRemoveItem(coin, 1)
				doSendMagicEffect(config[item.uid][1], CONST_ME_HITBYFIRE)
				doSendMagicEffect(getCreaturePosition(cid), CONST_ME_TELEPORT)
				doTeleportThing(cid, config[item.uid][2], FALSE)
				doSendMagicEffect(getCreaturePosition(cid), CONST_ME_TELEPORT)
			end
		else
			doSendMagicEffect(getCreaturePosition(cid), CONST_ME_TELEPORT)
			doTeleportThing(cid, config[item.uid], FALSE)
			doSendMagicEffect(getCreaturePosition(cid), CONST_ME_TELEPORT)
		end
	end
	return TRUE
end

The errors I got is this one when i step to the Mystic flame:

in function 'get tileitembyID'
