Help with Lerping?

How can I run a module script for lerping? I’ve used samfundev’s plugin to create a module and I’ve tried running it but it did not work as intended, it did not run at all, while printing worked.
plugin

I’ve tried

wait(2.5)

local x = require(script["Automatic Save"])

for i,v in pairs(x.Keyframes) do
	task.defer(function()
		wait(i)
		for Part,Position in pairs(v.HumanoidRootPart) do
			if Position.CFrame then
				print('works')
				script.Parent[Part].CFrame:Lerp(Position.CFrame,0.2)
				end
		end
	end)
	
end

with that I also tried looking on devforum but found nothing on it.
