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()
