attempt to index field 'DriveSeat' (a nil value) HELP NEEDED ASAP?

Im trying to make the fuel value appear on screen so the player can see how many liters they have.

while wait(3) do
    local player = game.Players.LocalPlayer
print("GOT THE NAME")
    local GoKart = player.name .. "'s GoKart"
print(GoKart)
    local Fuel = GoKart.DriveSeat.Fuel.Value
    script.Parent.Liters.Text = tostring(Fuel).."L"
end
