[AlexWo]

Hey I have a problem that my gui don't disapear when i click on the exit button

LSPolice = createMarker( 1554, -1675, 15.28, "cylinder", 1.5, 0, 0, 255) 
  
  
function MarkerHit ( hitPlayer, matchingDimension ) 
    outputChatBox ( getPlayerName(hitPlayer) .. ", you entered the Police-Job Marker in LS", 255, 255, 0 ) 
    local policeWindow = guiCreateWindow ( 0.25, 0.25, 0.4, 0.4, "Policejob LS", true ) 
    local policePanel = guiCreateTabPanel ( 0, 0.1, 1, 1, true, policeWindow )       -- create a tab panel which fills the whole window 
    local policeMap = guiCreateTab( "Job Information", policePanel )   
    guiCreateLabel(0.02, 0.04, 0.94, 0.2, "Welcome to the Police Department in Los Santos", true, policeMap) 
    guiCreateLabel(0.02, 0.08, 0.94, 0.92, "Press 'Accept' to accept the Job and get your Equipment", true, policeMap) 
    guiCreateLabel(0.02, 0.12, 0.94, 0.92, "Press 'Exit' to close this gui and exit", true, policeMap) 
    exitbutton = guiCreateButton( 0.5, 0.5, 0.1, 0.05, "Exit", true, policeMap ) 
    acceptbutton = guiCreateButton( 0.3, 0.5, 0.1, 0.05, "Accept", true, policeMap ) 
    showCursor ( true )   
end 
addEventHandler ( "onClientMarkerHit", getRootElement(), MarkerHit ) 
  
function wclose(state) 
 if state == "left" then 
  if source == exitbutton then 
   guiSetVisible(policeWindow, false) 
   showCursor(false) 
  end 
 end 
end 
addEventHandler("onClientGUIClick", getRootElement(), wclose) 
  
  

Would be pretty cool if somebody could help me

The policeWindow is only valid inside the first function as it is a local variable and I do NOT suggest making it a global variable. Try to rethink your functions.

Thanks for the very fast answer

But what exactly will happen if I make it not "local"?

That script will create the GUI everytime you hit the marker, so you should destroy these GUI elements once you click "Exit".
