Hey.. i can fix this script please...

  
local ROOT = getRootElement() 
local ME = getLocalPlayer() 
  
local Timer = nil 
  
addEvent("ghost_off", true) 
addEventHandler("ghost_off", ROOT, function() 
    exports.race:nametaglock(false) 
    Timer = setTimer(turn_off, 200, 0) 
end) 
  
function turn_off() 
    local myvehicle = getPedOccupiedVehicle(ME) 
    local x, y, z = getElementPosition(ME) 
    for _, vehicle in ipairs(getElementsByType("vehicle")) do 
        local c = isElementCollidableWith(myvehicle, vehicle) 
        local cp = getElementData(getVehicleController(vehicle), 
            "race.checkpoint") 
  
        if vehicle ~= myvehicle and c == false and cp >= 6 then 
            local vx, vy, vz = getElementPosition(vehicle) 
            local distance = getDistanceBetweenPoints3D(vx, vy, vz, 
                x, y, z) - getElementRadius(vehicle) - 
                getElementRadius(myvehicle) 
            if (distance > 5) then 
                setElementCollidableWith ( myvehicle, vehicle, true ) 
                setElementAlpha ( vehicle, 255 ) 
                setElementAlpha ( getVehicleController( vehicle ), 255 ) 
            else 
                setElementCollidableWith ( myvehicle, vehicle, false ) 
                setElementAlpha ( vehicle, 160) 
                setElementAlpha ( getVehicleController( vehicle ), 160 ) 
            end 
        end 
    end 
end 
  
addEventHandler("onClientMapStopping", ROOT, function() 
    killTimer(Timer) 
end) 
  
addEventHandler("onClientMapStarting", ROOT, function() 
    exports.race:nametaglock(true) 
end) 
  

When a player passes checkpoint (cca 6 cp) so ghostmode will automatically off... but idk where is problem. please help

PS: Its only for race mod.
