luaGetPlayerStorageValue(). Player not found

[mpa]

What is wrong?

error:

luaGetPlayerStorageValue(). Player not found

local compareTime = 60 * 60 * 1000
local scroll = 1959

local currentValue = getPlayerStorageValue(cid, 9798)
    if currentValue == -1 then
        currentValue = os.time()
    end

function onUse(cid, item)
    if hasCondition(cid, CONDITION_INFIGHT) == TRUE and item.itemid == scroll then
        doPlayerSendCancel(cid, "You may not use this scroll while in-fight!")
        return FALSE
    end

    if (os.time() - currentValue) >= compareTime and hasCondition(cid, CONDITION_INFIGHT) == FALSE and item.itemid == scroll then
        doSendMagicEffect(getCreaturePosition(cid), CONST_ME_POFF)
        doTeleportThing(cid, getTownTemplePosition(getPlayerTown(cid)), FALSE)
        doSendMagicEffect(getCreaturePosition(cid), CONST_ME_TELEPORT)
        doPlayerSendTextMessage(cid,19,"You have been teleported to your home town!")
        setPlayerStorageValue(cid, 9798, os.time())
    else
        doPlayerSendCancel(cid, "You can only use this scroll once every hour.")
end
return TRUE
end

Edit: When I'm on a regular player, I don't get any errors. Just cancelmessage "You can only use this scroll once every hour."

local currentValue = getPlayerStorageValue(cid, 9798)
    if currentValue == -1 then
        currentValue = os.time()
    end

You have to place this under onUse function
