math.random - What is wrong?

[Lukanio]

Script not working:

function onStepIn(cid, item, position, lastPosition, fromPosition, toPosition, actor)
local chance = math.random(1,4)
if chance == 1 then
return doTeleportThing(cid, {x=738, y=1008, z=7})
elseif chance == 2 then
return doTeleportThing(cid, {x=739, y=1008, z=5})
elseif chance == 3 then
return doTeleportThing(cid, {x=738, y=1007, z=3})
elseif chance == 4 then
return doTeleportThing(cid, {x=739, y=1006, z=1})
else
doTeleportThing(cid, fromPosition)
doPlayerSendCancel(cid, "Sorry, not possible.")
end
return true
end
