Solved talkactions - getPlayerPosition, getting boolean value error

[Dridia]

I've created a script, when i type the word "tp" in a specific position i want to get teleported. but i get an error

My talkactions.xml:

<talkaction words="tp" script="custom/looktype-tp.lua"/>

My .lua script:

local pos = getPlayerPosition(cid)
local newPos = {x=1000, y=1000, z=7}

function onSay(cid, words, param)
	if pos.x == 1000 and pos.y == 1000 and pos.z == 7 then
		doTeleportThing(cid, newPos)
		doSendMagicEffect(getPlayerPosition(cid), 12)
	else
		doPlayerSendTextMessage(cid, MESSAGE_STATUS_WARNING, "You have to stand on the glowing switch!")
		doSendMagicEffect(getPlayerPosition(cid), 2)
	end
end

The error i recieve:

[04/11/2012 13:38:59] Lua Script Error: [TalkAction Interface]

I don't understand why my variable is declared to a boolean variable... please help me!

Try putting "local pos = " below the function.
