Help with marker hit

[Michcio]

I have problem with hitting a marker. I want to do sth like only one player can open gui window at the same time.

My code:

function ukryj () 
    guiSetVisible(oknolicencja,false) 
    showCursor(false) 
    unbindKey("z","down",ukryj) 
    setElementData(marker,"wolne",false) 
    setElementData(getLocalPlayer(),"marker_prawko",false) 
end 
  
function pokaz2 (hitPlayer, matchingDimension) 
if source == marker then 
for k,v in ipairs(getElementsByType("player")) do 
    if getElementData(v,"zdaje_prawko") == false then 
    bindKey("z","down",pokaz) 
    setElementData(hitPlayer,"marker_prawko",true) 
    elseif getElementData(v,"zdaje_prawko") == true then 
    unbindKey("z","down",pokaz) 
    callServerFunction("outputChatBox","***| Gracz "..getPlayerName(v).." teraz zdaje prawko! |***",hitPlayer,255,255,255) 
    end 
end 
end 
end 
addEventHandler("onClientMarkerHit",marker,pokaz2) 
  
function pokaz () 
    guiGridListSetItemText ( glicencja, row1, kol1, "Prawko kat.B", false, false ) 
    guiGridListSetItemText ( glicencja, row1, kol2, "2000$", false, false ) 
    guiSetVisible(oknolicencja,true) 
    setElementData(gracz,"zdaje_prawko",true) 
    showCursor(true) 
    centerWindow(oknolicencja) 
    bindKey("x","down",ukryj) 
    outputChatBox("***| Aby zamknac okienko wcisnij 'x' |***",255,255,255) 
end

end 
end 
end 
addEventHandler("onClientMarkerHit",marker,pokaz2) 
  
function pokaz () 
    guiGridListSetItemText ( glicencja, row1, kol1, "Prawko kat.B", false, false ) 
    guiGridListSetItemText ( glicencja, row1, kol2, "2000$", false, false ) 
    guiSetVisible(oknolicencja,true) 
    setElementData(gracz,"zdaje_prawko",true) 
    showCursor(true) 
    centerWindow(oknolicencja) 
    bindKey("x","down",ukryj) 
    outputChatBox("***| Aby zamknac okienko wcisnij 'x' |***",255,255,255) 
end

Nothing changed.

Where is the marker created? you should create it server side, when a player hits it, set a variable, when another hits, check that variable, and when they leave, set it to false.

as solid say

where the marker?

It's only part of my code. Marker is created at the beggining of code.

Do what I said above.
