Teleport error

[Dominik ms]

pos = getCreaturePosition(pid)
	for i = 0, 7 do
		ground = {x=pos.x, y=pos.y, z=0+i}
		if isWalkable(ground) == true then
			doTeleportThing(pid, ground, true)
			doRemoveConditions(pid, false)
			return true
		end
	end

works perfect, but if tile not found i have error
I am on pos z = 0, use script, now if tile under my self is walkable the i am teleporting down, up to ground tile (7).
