Destroy command not working in Trail script?

I have a gui that allows players to select a trail from a list. They have to click on a button to enable the trail and then a button will appear that allows them to disable it by destroying the trail. The enabling part works fine but the disabling/destroying part isn't. Please help me fix it.

The GUI is located in StarterGui and it contains Button1 which has the Enabling part, in a local script, and also Destroy1 button which has the Disabling part, also in a local script. When the trail is enabled, it will under the HumanoidRootPart.

Enabling Script:

local player = game.Players.LocalPlayer
local give = script.Parent

give.MouseButton1Click:connect(function()
	local character = player.Character
	local trailClone = Instance.new("Trail", character.Head)
	local HP = character.Head.NeckRigAttachment
				local HRP = character.HumanoidRootPart.RootAttachment
				local trailClone = Instance.new("Trail", character.Head)
				trailClone.Parent = character.HumanoidRootPart
				trailClone.Attachment0 = HP
				trailClone.Attachment1 = HRP
				trailClone.Lifetime = 1
				trailClone.Texture =  "http://www.roblox.com/asset/?id=908770358" 
				trailClone.TextureMode = "Stretch"
				trailClone.TextureLength = 1
				trailClone.LightEmission = 0.2
				trailClone.Transparency = 0.5
				trailClone.MinLength = 0.1
script.Parent.Parent.Destroy1.Visible = true

end)

Disabling Script:

local player = game.Players.LocalPlayer
local give = script.Parent

give.MouseButton1Click:connect(function()
	local char = player.Character
	char.HumanoidRootPart.Trail:Destroy()
	script.Parent.Visible = false
end)
