part is not a valid member of workspace/model?

i cant figure out for the life of me how this isnt working

wait(3)
script.Parent:MoveTo(game.Workspace.one.Position)
wait(.5)
script.Parent.Jump = true
wait(.4)
script.Parent:MoveTo(workspace.Model.two.Position)
wait(.2)
script.Parent.Jump = true
wait(.7)
script.Parent.Jump = true
script.Parent:MoveTo(workspace.Model.three.Position)
wait(.4)
script.Parent.Jump = true
--script.Parent:MoveTo(game.Workspace.iDests.Dest9.Position)
wait(1)
script.Parent:MoveTo(workspace.three.Position)
wait()
--script.Parent:MoveTo(game.Workspace.iDests.Dest9.Position)
wait(1)
script.Parent.Script:Remove()
--script.Parent:MoveTo(Vector3.new(3.67, 5.7, -13.5))

it outputs: two is not a valid member of Model

remove isn't recommended, it just sets the parent to nil. Think of it as; Cut, and delete. If you cut an object you're setting it's parent to nil, and if you delete it. It's gone forever.

Remove just sets the parent to nil.

#Why is remove not recommended

:Remove, causes untracked memory. Many developers suffer from untracked memory. Untracked memory can cause game lag, unplayable game, and even shutdowns.

But untrackedmemory is another topic i don't want to get too in-depth on.
