Problem with my armour, I cant pick it?

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.

make sure the armor is actually classed as a tool and it has a part called Handle
