how to create gui when player on the marker?

[Andrew75t]

I created a gui, it opens when the player logs into the server. How do I make the window open when the player steps on the marker?

Client 

function createWSWindow()
    local X = 0.375
    local Y = 0.375
    local Width = 0.25
    local Height = 0.25
    WSWindow = guiCreateWindow(X, Y, Width, Height, "WEAPONSHOP", true)
end

addEventHandler("onClientResourceStart", getResourceRootElement(getThisResource()), 
    function ()
        createWSWindow()
    end
)

function createWSWindow()
	local X = 0.375
	local Y = 0.375
	local Width = 0.25
	local Height = 0.25
	WSWindow = guiCreateWindow(X, Y, Width, Height, "WEAPONSHOP", true)
end

addEventHandler("onClientResourceStart", getResourceRootElement(getThisResource()), 
	function ()
		createWSWindow()
	end
)

Server

local WeaponShopMarker = createMarker(1790.7, -1699.3, 12.6, "cylinder", 2.5, 0, 0, 0, 50)
		addEventHandler("onMarkerHit", WeaponShopMarker, function(ThePlayer)
		addPedClothes ( ThePlayer, "tshirtzipcrm", "tshirt", 0 ) 
end)

client 

local window1 = guiCreateWindow(0.22, 0.22, 0.57, 0.61, "bla", true) 
guiWindowSetSizable(window1, false) 
guiSetVisible(window1,false) 
local button1 = guiCreateButton(0.03, 0.83, 0.94, 0.15, "123", true, window1) 
local text1 = guiCreateLabel(0.03, 0.07, 0.94, 0.75, "321", true, window1)
guiLabelSetHorizontalAlign(text1, "center", false)

 
   
addEvent("showGUI",true) 
addEventHandler("showGUI",getRootElement(), 
function () 
    if ( guiGetVisible(window1) == false ) then 
    guiSetVisible(window1,true) 
    showCursor(true) 
    end 
end) 




local function guzik()
	guiSetVisible(window1, false)
	showCursor(false, false)
end
addEventHandler("onClientGUIClick", button1, guzik, false)

server
 

addEventHandler("onResourceStart",resourceRoot, 
function () 
        local marker = createMarker(1542.67529, -1448.50500, 12.54688, "cylinder", 1.5, 0, 255, 0, 180) -- USE YOUR OWN X/Y/Z
        --local blip = createBlipAttachedTo(marker, 1) -- pokazuje naam marker na gps i mapie
        setElementInterior(marker, 0) 
        setElementDimension(marker, 0) 
        addEventHandler("onMarkerHit",marker,onMarkerHit) 
end) 
  
function onMarkerHit(hitPlayer, matchingDimension) 
     if not matchingDimension then return end 
     if ( getElementType (hitPlayer) == 'player' ) then 
     triggerClientEvent(hitPlayer,"showGUI",hitPlayer) 
    end 
end

just change X/Y/Z and shloud working  @Andrew75t
