Script not running when moved? [Solved]

So I have a script inside a model in Replicated Storage that welds the all of the parts together. The script works perfectly fine, but it's in Replicated Storage so it won't run, right? The wiki says that the script runs when it is moved into any service that it can run it, but it's not doing that. It's moving the parts but the weld script isn't welding the parts together. Help?!

--\\ Services
local JointsService = game:GetService('JointsService')

--\\ Variables
local Model = script.Parent
local WeldPart = Model.PrimaryPart

function Weld()
	local function WeldParts(Part, handle)
		Part.Anchored = false
		local weld = Instance.new("Weld")
		weld.Part0 = handle
		weld.Part1 = Part
		weld.C0 = handle.CFrame:inverse()
		weld.C1 = Part.CFrame:inverse()
		weld.Parent = JointsService
	end
	
	for _,obj in pairs (Model:GetChildren()) do
		if obj:IsA ("BasePart") or obj:IsA ("UnionOperation") then
			WeldParts (obj, WeldPart)
		end		
	end
end

Weld()
wait (1)
script:Destroy()
