Problem with my armour, I cant pick it? [closed]

Hi! I have done an armour for my security in my game and the script to get the armour dont work

local debounce = true

function onTouched(hit)
    if debounce == true then
        debounce = false
    if hit.Parent:findFirstChild("Humanoid") ~= nil and hit.Parent:findFirstChild("Chest") == nil then
        local g = script.Parent.Parent.Chest:clone()
        g.Parent = hit.Parent
        local C = g:GetChildren()
        for i=1, #C do
            if C[i].className == "Part" or "Union" then
                local W = Instance.new("Weld")
                W.Part0 = g.Middle
                W.Part1 = C[i]
                local CJ = CFrame.new(g.Middle.Position)
                local C0 = g.Middle.CFrame:inverse()*CJ
                local C1 = C[i].CFrame:inverse()*CJ
                W.C0 = C0
                W.C1 = C1
                W.Parent = g.Middle
            end
                local Y = Instance.new("Weld")
                Y.Part0 = hit.Parent.Torso
                Y.Part1 = g.Middle
                Y.C0 = CFrame.new(0, 0, 0)
                Y.Parent = Y.Part0
        end

        local h = g:GetChildren()
        for i = 1, # h do
            if h[i].className == "Part" or "Union" then
                h[i].Anchored = false
                h[i].CanCollide = false
            end
        end

    end
    wait(1)
    debounce = true
    end
end

script.Parent.Touched:connect(onTouched)

If you can help Thanks you very much.
