What is wrong with this movement script?

I am using a movement script that controls where a part moves to. I was trying to replicate an example but this is what I got.

local model = script.Parent
local Moving = model.Moving
local Stay = model.stay
local Seat = Seat
local BodyPosition = Moving.BodyPosition

While true do
	BodyPosition.position = Stay.Position
	Wait(6)
	BodyPosition.position = Seat.Position
	wait(6)
	
end

Thank you. The error is found in the keyword true. I was wondering if it was outdated or I did something wrong. I also don't plan on using the loop but for practice I am doing loops and movement so if you guys could help it would be amazing.

Your error isn't from the word 'true' -- The output probably said something along the lines of '= expected near true', as it expects 'While' to be a variable. This is because 'While' should be lowercase:

local model = script.Parent
local Moving = model.Moving
local Stay = model.stay
local Seat = Seat
local BodyPosition = Moving.BodyPosition

while true do -- The error
    BodyPosition.position = Stay.Position
    Wait(6)
    BodyPosition.position = Seat.Position
    wait(6)

end

Hope this helped.

Here is the more updated script it doesn't have any Syntax errors however it doesn't want to do anything

local model = script.Parent
local Moving = model.Moving
local Stay = model.Stay
local Seat = game.workspace.Seat
local BodyPosition = Moving.BodyPosition

while true do
	BodyPosition.position = Stay.position
	wait(6)
	BodyPosition.position = Seat.position
	wait(6)
end

Also here is the Output
