I'm trying to have a part light up when it has a certain value inside of it and when the mouse hovers over it, and then stop lighting up when the mouse stops hovering over it. While this is working there is a bug that occurs when I spam it between two parts with the value. It lights up one and when I move the mouse away it stays lit up. Here is the script: 

--\\ Bools
local TargetPart = nil
local MouseDebounce = false

--// Inventory Module
local Inventory = {}

local InventoryGui = PlayerGui:WaitForChild'Inventory'
local Blur = InventoryGui:WaitForChild'Blur Background'
local Items = Blur:WaitForChild'Items'

MouseMove = function()
	if MouseDebounce == false then 
		MouseDebounce = true
		local Target = Mouse.Target
		if Target ~= nil then
			if Target:FindFirstChild'ItemID' then 
				if Client:DistanceFromCharacter(Target.Position) < 20 then
					if Target:FindFirstChild'SelectionBox' == nil  then
						TargetPart = Target
						local NewSelectionBox = SelectionBox:clone()
						NewSelectionBox.Parent = Target
						NewSelectionBox.Adornee = Target		
					end
				end
			elseif not Target:FindFirstChild'ItemID'  and TargetPart ~= nil then
				print ('True')
				local Sb = TargetPart:FindFirstChild'SelectionBox'
				if Sb then
					Sb:destroy()
					TargetPart = nil
				end
			end
		end
		MouseDebounce = false
	end
end
	
	
Mouse.Move:connect(MouseMove)
