Grabbing objects by using welds?[Solved]

So I suck at math lmao or my knowledge of the roblox API is not large enough. I would like to know to grab item with a certain keybind. Here's what I came up with :

Character.GrabRightArm.Touched:Connect(function(hit)
	if hit and RG == true then
	-- Checks for Welds
		local Weld = Character.GrabRightArm:FindFirstChild("Weld")
		if Weld and Weld.Part1 ~= hit then
			Weld:Destroy()
			local Weld = Instance.new("Weld", Character.GrabRightArm)
			Weld.Part0 = Weld.Parent
			Weld.Part1 = hit
			Weld.C0 = Weld.Part0.CFrame
			Weld.C1 = Weld.Part1.CFrame
			hit.Massless = true
		elseif Weld == nil then
			local Weld = Instance.new("Weld", Character.GrabRightArm)
			Weld.Part0 = Weld.Parent
			Weld.Part1 = hit
			Weld.C0 = Weld.Part0.CFrame
			Weld.C1 = Weld.Part1.CFrame
			hit.Massless = true
		end
	end
end)

This is the only part required because it's where the weld is being made.
