Stamina Modify Problem

[Ascuas Funkeln]

Hello i have little problem, im new in making scripts and need little help

I want turn"Stamina" into "EXP Boost"
I make Item that Refill Stamina by "x" minutes, but now i have bigger problem.
Thats should work like that:
0 Stamina = Normal EXP (1X)
More than 0 Stamina = Double EXP (2x)

config.lua of TSF cant set this. Soo i make this, but its not work and idk why xD

  function onLogin(cid)
        local staminaMinutes = getPlayerStamina(cid)
        if staminaMinutes > 1 then
        getPlayerRates(cid)
        doPlayerSetExperienceRate = 2.0
        elseif staminaMinutes == 0 then
        getPlayerRates(cid)
        doPlayerSetExperienceRate = 1.0
        end
        end

And when i launch server i try login. There is no errors, but cant login to game.

OK, i fix it. This work

  function onLogin(cid)
        local config = {
    expend = 0,
    expstart = 1}
        staminaMinutes = getPlayerStamina(cid)
        if staminaMinutes >= config.expstart then
        doPlayerSetRate(cid, SKILL__LEVEL, 2)
        else if staminaMinutes == config.expend then
        doPlayerSetRate(cid, SKILL__LEVEL, 1)
        end
        end
        return true
        end

But need relog to activate, i try add onUse and onThink fuction but anything work xD Any ideas? I try use onUse function with item that add stamina, but this duplicate item and not work, maybe instert this "stamina script" into "staminarefil" script will solve problem?

How rly work function "onThink"
Now problem is, make it working on using item, and when stamina end in game to stop bonus. xD
