How to change touch giver to clicks giver by GUI?

Place this LocalScript inside of the button in your menu GUI.

script.Parent.MouseButton1Click:Connect(function()
	local g = script.Parent.Parent.Chest:clone() -- I'm not where your original script was located, but check to make sure that this is correctly referencing g still.
	local player = game.Players.LocalPlayer --  player that clicked on the GUI
        g.Parent = player
        local C = g:GetChildren()
        for i=1, #C do
		if C[i].className == "Part" or C[i].className == "UnionOperation" or C[i].className == "MeshPart" 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

                	local Y = Instance.new("Weld")
                	Y.Part0 = player.Character.Humanoid.Torso
                	Y.Part1 = g.Middle
                	Y.C0 = CFrame.new(0, 0, 0)
                	Y.Parent = Y.Part0

			local h = g:GetChildren()
        		for i = 1, # h do
            			h[i].Anchored = false
            			h[i].CanCollide = false

        		player.Saude.Protecao.VestProtect.Value = 50
        		player.Saude.Protecao.VestVida.Value = 100
			end
		end
	end
end)

Hope this helps!
