Problem with duty

[Simi23]

Hello! I have make a duty script, and its doesn't working. Can anyone solve it? 

Server: 

addEvent("addArmor", true)

function addArmor()
    setPedArmor(source, 100)
end

addEventHandler("addArmor", getRootElement(), addArmor)

function pdduty(player)
    local x, y, z = getElementPosition(player)
    local pickup = createPickup(x + 3, y, z, 3, 1242)
    colshape = getElementColShape(pickup)
    addEventHandler("onColShapeHit", colshape, openwindow)
    addEventHandler("onColShapeLeave", colshape, closewindow)
    addEventHandler("onPickupUse", pickup, 
    function()
        cancelEvent()
    end)
end
addCommandHandler("pdduty", pdduty)

function openwindow(hitElement, matchingDimension)
    if matchingDimension and getElementType(hitElement) == "player" then
        triggerClientEvent("openwindow", hitElement)
        
    end
end



function closewindow(hitElement, matchingDimension)
    if matchingDimension and getElementType(hitElement) == "player" then
        triggerClientEvent("closewindow", hitElement)
    end
end

Client: 

sx, sy = guiGetScreenSize()

addEvent("openwindow", true)

function changeDuty()
    if getElementData(lPlayer, "duty", "0") then
        lPlayer = getLocalPlayer()    
        givePedWeapon(lPlayer, 24)
        givePedWeapon(lPlayer, 31, 180)
        triggerServerEvent("addArmor", getRootElement())
        setElementData(lPlayer, "duty", "1")
    end
end

function draw()
    dxDrawRectangle(sx * 0.4, sy * 0.65, sx * 0.2, sy * 1.0, tocolor(0,0,0,150))
    dxDrawText("Duty: [E]", sx * 0.45, sy * 0.7)
end

function openwindow()
    addEventHandler("onClientRender", getRootElement(), draw)
    bindKey("e", "down", changeDuty)
end

addEventHandler("openwindow", getRootElement(), openwindow)

addEvent("closewindow", true)

function closewindow()
    removeEventHandler("onClientRender", getRootElement(), draw)
    unbindKey("e", "down", changeDuty)
end

addEventHandler("closewindow", getRootElement(), closewindow)

The meta doesn't have any problems, for sure.

Tell us what errors you're facing.

What i think is: If i hit the placed collision of the pickup, it shows me the window, and i can press e to receive my armor, deagle, and an M4. But if i hit that pickup, it happens nothing. I think because pickups has no collision.

Use onPickupHit

I know, but pickups have no "onPickupLeave" event. I'm think i am gonna use a hidden marker and make the pickup do nothing.
