random teleport - need help

[straher]

Hi. I've found on forum this kind of teleport rune, however I need it to be transformated to movement action with specified actionID

here's the script

function onUse(cid, item, frompos, item2, topos)

local pos = 
 {x=10, y=10, z=7},
 {x=20, y=20, z=7},
 {x=30, y=30, z=7},
 {x=40, y=40, z=7}} -- position to teleport.

local rand = math.random(1, #pos)
doTeleportThing(cid, pos[rand])
doSendMagicEffect(10, pos[rand])

end
return TRUE
end

Help! Please!
