TDM Cars (Passenger Fixes) apparently do nothing at all

[AngryMuffins]

So I have on my server, the following things
- TDM Base Pack
- 5 TDM Car Packs
- Their "Passenger Fix" addons ([URL="http://steamcommunity.com/sharedfiles/filedetails/?id=234044221"]example[/URL])

And when a second person tries to get into a vehicle nothing happens, it doesn't work.
Why is this?

Here is the code for one of the cars for an example:

local V = {
			Name = "Mercedes SLS AMG", 
			Class = "prop_vehicle_jeep",
			Category = "TDM Cars",
			Author = "TheDanishMaster, Turn 10",
			Information = "A drivable Mercedes SLS AMG by TheDanishMaster",
			Model = "models/tdmcars/mer_slsamg.mdl",
					VC_ExtraSeats = { //Can be an infinite amount of seats, Pos and ExitPos can be a simple Vector() or an attachment name, other options are self explanatory.
						{Pos = Vector(22, -22, 20), Ang = Angle(0, 0, 8), EnterRange = 80, ExitAng = Angle(0, -90, 0), Model = "models/props_phx/carseat2.mdl", ModelOffset = Vector(12, 0, 4), Hide = true, DoorSounds = true, RadioControl = true}
						},							
						
						KeyValues = {
							vehiclescript	=	"scripts/vehicles/TDMCars/slsamg.txt"
							}
			}
list.Set("Vehicles", "slsamgtdm", V)

Do you have an actual passenger mod installed tho?
