How to make clicking a part give a gear?

Door = script.Parent
cooldown = 5 --How much time in seconds it takes for the door to open again. change if you wish.
value = false

function OnClicked()
	if (value == false) then
		value = true
	end
   local cloned = game.Lighting.Water:Clone()
    game.Lighting.Water:Clone().Parent = game.Players.LocalPlayer.Backpack


    Door.ClickDetector.MaxActivationDistance = 0
	wait(cooldown)
	
	value = false
    Door.ClickDetector.MaxActivationDistance = 10
end

script.Parent.ClickDetector.MouseClick:connect(OnClicked)

I try clicking on Door to get the 'Water' gear but it says LocalPlayer is a nil value. How can I tell it to give the gear to whoever is clicking?

It works in the studio, but not in the real game.

Door = script.Parent
cooldown = 5 --How much time in seconds it takes for the door to open again. change if you wish.
value = false

function OnClicked(player)
	if (value == false) then
		value = true
	end
   local cloned = game.Lighting.Water:Clone()
    game.Lighting.Water:Clone().Parent = player

    cloned.Handle.Anchored = false
    cloned.Handle.Locked = false

	Door.CanCollide = false
    Door.ClickDetector.MaxActivationDistance = 0
	wait(cooldown)
	
	value = false
    Door.ClickDetector.MaxActivationDistance = 10
end

script.Parent.ClickDetector.MouseClick:connect(OnClicked)

Door = script.Parent
cooldown = 5 --How much time in seconds it takes for the door to open again. change if you wish.
value = false

function OnClicked(player)
    if (value == false) then
        value = true
    end
   local cloned = game.Lighting.Water:Clone()
    game.Lighting.Water:Clone().Parent = player.Backpack -- Notice this

    cloned.Handle.Anchored = false
    cloned.Handle.Locked = false

    Door.CanCollide = false
    Door.ClickDetector.MaxActivationDistance = 0
    wait(cooldown)

    value = false
    Door.ClickDetector.MaxActivationDistance = 10
end

script.Parent.ClickDetector.MouseClick:connect(OnClicked)

You were parenting your tool to the player itself rather than the player's Backpack. Hopefully your script works now.

Best regards!
