Event in function

[Rutex]

Hi guys. I have small problem. I need to have event listener in function. Server:

  
function enterVehicle( theVehicle, seat, jacked) 
... some code 
if(CurrectCarID == 437) then 
        if(seat == 0)then 
            triggerClientEvent( Player, "EnterBus",getRootElement() ) 
                        addEventHandler( "BusMarsh1",getRootElement(  ), function () 
                        log("marsh1") 
end)  
  

its send on client event, that activate the gui, and return the selected button in event

The problem is, in every car enter, the event is dupe.

for example. 1 st. enter - its print only 1 time "marsh1". In next enter car, its print 2 times "marsh1", in 3 enter 3, and etc....

How i can do this right? or fix? Without this dupe.

P.s. Log. func.

  
function log( Msg ) 
    outputChatBox( Msg,getRootElement(  )) 
end

Because every time the function enterVehicle is called, a new event handler is created for "BusMarsh1". You'll have to remove it using removeEventHandler.

Yes. I know why its dupe. For me was intresing how i can " fix " it. I was think here is special event listener for this.

Thank you:)
