I get the error of: Engine is not a valid member of Model
Then it referenced me to line 154 of my script which is
v = script.Parent.Parent
--Skip Line--
v.Engine.BF.velocity = v.Engine.CFrame.lookVector * script.Parent.SpdValue.Value * seat.Throttle
Here's the layout of the model Model >Body >sOMEBRICKS >Parts >VehicleSeat >Lights >Lights >Lights >Lights >Engine
any clue why? Am I one Parent extra?

Can you also show where the Script is? A suggestion to format the hierarchy would be to use the Lua environment and tabs to show children.
