What is wrong?

[Ecstacy]

Hello,

I'm having some problems with this script that I can't figure out :s.

The problem is that when i'm in the outfit 'rat', it doesn't work, but when I'm in the outfit 'mew', It works 100%.

local s = {
	{name = 'mew', st = 100},
	{name = 'rat', st = 101}
}
function onSay(cid, words, param, channel)
	local v = getCreaturePosition(cid)
	local up, down = {x = v.x, y = v.y, z = v.z-1}, {x = v.x, y = v.y, z = v.z+1}
	local r = s[1]
	if words == '/flyup' then
		if getPlayerStorageValue(cid, r.st) == 1 then
			if getTileItemById(up, 460).uid > 0 then
				doTeleportThing(cid, up, true)
				doSendMagicEffect(up, 10)
				doCreatureSay(cid, 'Up!', 19)
				return doPlayerSendTextMessage(cid, 20, 'You have flown up.')
			else
				return doPlayerSendTextMessage(cid, 20, 'You can\'t fly up here.')
			end
		else
			return doPlayerSendTextMessage(cid, 20, 'You aren\'t mounted.')
		end
		return true
	end
	if words == '/flydown' then	
		if getPlayerStorageValue(cid, r.st) == 1 then
			if getTileItemById(down, 460).uid > 0 then
				doTeleportThing(cid, down, true)
				doSendMagicEffect(down, 10)
				doCreatureSay(cid, 'Down!', 19)
				doPlayerSendTextMessage(cid, 20, 'You have flown down.')
			elseif v.z == 6 then
				if getTileItemById(v,460).uid > 0 then
					if doTeleportThing(cid, down, true) then
						doSendMagicEffect(down, 10)
						doCreatureSay(cid, 'Down!', 19)
						doPlayerSendTextMessage(cid, 20, 'You have flown down.')
					else
						return doPlayerSendTextMessage(cid, 20, 'You can\'t fly down here.')
					end
				else
					return doPlayerSendTextMessage(cid, 20, 'You can\'t fly down here')
				end
			else
				return doPlayerSendTextMessage(cid, 20, 'You can\'t fly down here.')
			end
		else
			return doPlayerSendTextMessage(cid, 20, 'You aren\'t mounted.')
		end
		return true
	end
end
