i can not see my proximitypromp but its in the workspace?

So im makeing handcuffs in my game and what im doing is that when someone hold's the handcuffs it detect the colest player by them and adds a proximityprompt to the player's humanoidrootpart. It add the proximitypromp to the player humanoidrootpart but i can not see the proximitypromp. on line 10 i added a line that made it so it cant add a proximitypromp to the player who is holding the handcuffs. But the weird thing is that if i remove that line for some reson it works. but the proximitypromp go on the player body who's is hold the handcuffs witch is not what i want. Can any one help me?

And Here My Code:

local Players = game:GetService("Players")
local Player = Players.LocalPlayer

local AddDetector = Instance.new("ProximityPrompt")

local range = 10

script.Parent.Equipped:Connect(function()
	for i, v in	pairs(game.Workspace:GetChildren()) do
		if v:FindFirstChild("Humanoid") and v ~= Player.Character then
			local vHumanoid = v.Humanoid
			if (Player.Character.HumanoidRootPart.Position - v.Humanoid.Parent.HumanoidRootPart.Position).magnitude < range then
				AddDetector.Parent = vHumanoid.Parent.HumanoidRootPart
				AddDetector.MaxActivationDistance = range
				AddDetector.ActionText = "Arrest"
				AddDetector.HoldDuration = 2
				AddDetector.KeyboardKeyCode = "E"
			end
		end
	end
end)

AddDetector.Triggered:Connect(function()
	
end)
