onepart = "0,0,5" twopart = "5,0,0" k = Instance.new("Part",game.Workspace.JohnJohniamm55.Torso) k.CFrame = game.Workspace.JohnJohniamm55.Torso.CFrame * CFrame.new(5,0,0) k.Anchored = true wait(1) k.Vector3 = twopart:Lerp(onepart, 1)
the error is
Workspace.Script:1: attempt to call method 'lerp' (a nil value)
http://wiki.roblox.com/index.php?title=Lerp might help your understanding a bit more.
When you called the Lerp, there should be three values instead of 2. Three values is calling a vector three, which I assume you are trying to call. 2 values call's a quaternion lerp.Also to save you some time, instead of
game.Workspace.JohnJohniamm55.Torso.CFrame, make a variable named "Player" and write Player = game.Players.LocalPlayer. next where "game.Workspace.JohnJohniamm55.Torso.CFrame" is write "Player.Torso.CFrame". This will save you a lot of time. Be sure to take a look at the website if you still don't understand your problem
