[damien111]

I am trying to create my taxi script from scratch. I am not sure why it is not workng but it is not creating a marker. Also. any advice will be greatly appreciated. Thanks!

      pickedup = false 
      local id = getElementModel ( vehicle ) 
      
        local VehMarker = createMarker ( 1731.9326171875, 1927.2426757813, 10, "cylinder", 2, 0, 120, 255, 0 ) 
         local theTeam = createTeam ( "Taxi Drivers" ) 
        function startjob ( hitElement, matchingDimension ) 
            local elementType = getElementType ( hitElement ) 
            if ( elementType == "player" ) then 
            setPlayerTeam(source, theTeam) 
            setPlayerSkin(playerSource, 280) 
            
                    local x, y, z = getElementPosition ( hitElement ) 
                    local vehicle = createVehicle ( 597, x, y, z ) 
                    
                    if id == 420 then 
        function f() 
           pickup = createMarker(x, y, z, "cylinder", 2, 250, 250, 250) 
           pickupblip = createBlipAttachedTo(43, pickup) 
           dropoff = createMarker(a, b, c, "cylinder", 2, 250, 250, 250) 
           dropoffblip = createBlipAttachedTo(44, pickup) 
        end
