Cloning and welding a morph from ServerStorage to the Torso?

script.Parent.MouseButton1Down:connect(function()
    local Player = script.Parent.Parent.Parent.Parent.Parent
    if Player.Character:FindFirstChild("Humanoid") ~= nil and Player.Character:FindFirstChild("BTorso") ~= nil then
        local suit = game.ServerStorage.Morphs.Police.Standard["BTorso"]:Clone()
        suit.Parent = Player.Character
        local G = suit:GetChildren()
        for i=1, #G do
            if G[i].ClassName == "Part" or "UnionOperation" then
                local suitW = Instance.new("Weld")
                suitW.Part0 = suit.MainPart
                suitW.Part1 = G[i]
                local autoW = CFrame.new(suit.MainPart.Position)
                suitW.C0 = suit.MainPart.CFrame:inverse()*autoW
                suitW.C1 = G[i].CFrame:inverse()*autoW
                suitW.Parent = suit.MainPart
            end
            local bpW = Instance.new("Weld")
            bpW.Part0 = Player.Character["Torso"]
            bpW.Part1 = suit.MainPart
            bpW.C0 = CFrame.new(0,0,0)
            bpW.Parent = suit.MainPart
        end
        local f = suit:GetChildren()
        for i=1, #f do
            f[i].Anchored = false
            f[i].CanCollide = false
        end
    end 
end)

I ended up making this script so that I could use a GUI to clone and weld parts onto the players' torso. I'm not sure why it's not working? There's nothing in output, and nothing happens when I click the button. Any help?
