what the heck is wrong with this

[Davey]

    "Davey" type="script" name="engine" /> 
    "help.xml" type="client"/> 
      
     
     
     
    

this is one

    "Davey" type="script" name="Engine" /> 
    "help.xml" type="client"/> 
      
    client="1.3.1" server="1.3.1" /> 
     
    false
  
    

and this is 2 both of them dont dont work

function turnEngineOff ( theVehicle, leftSeat, jackerPlayer ) 
     
    if leftSeat == 0 and not jackerPlayer then 
         
        setVehicleEngineState ( theVehicle, false ) 
    end 
end 
-- add 'turnEngineOff' as a handler for "onPlayerExitVehicle" 
addEventHandler ( "onPlayerVehicleExit", getRootElement ( ), turnEngineOff ) 

this is the script lua

function toggleEngine(source) 
local vehicle = getPedOccupiedVehicle(source) 
    if vehicle then 
        if getVehicleEngineState(vehicle) then 
         setVehicleEngineState(vehicle, false) 
        else 
        setVehicleEngineState(vehicle, true) 
       end 
    end 
end 
addCommandHandler( "engine", toggleEngine ) 

and this is the command handler
