addEventHandler("onClientMarkerHit", jobMarker, function(player)
if player == localPlayer then
window = guiCreateWindow(500, 200, 250, 250, "*Tree JoB*", false)
memo = guiCreateMemo(100, 20, 240, 100, "Unicos RP Tree Job You can make esy money with rhis one# happy happy happy", false, window)
button = guiCreateButton(20, 150, 100, 100, "Accep", false, window)
closebutton = guiCreateButton(150, 150, 100, 100, "Close", false, window)
showCursor(true)
end
