how do i remove this error? keeps popping up...

the script works just fine, but i would lie to remove this error because it clogs up my output window.

the error is: Workspace.Buildings.WorkPlace_1.Floor_4.NPCs.Mark.QUEST03:33: attempt to index local 'Player' (a nil value)

local ReplicatedStorage = game:GetService("ReplicatedStorage")
local QuestLibraries    = ReplicatedStorage:FindFirstChild("QuestService")

local Quests  = require(QuestLibraries:FindFirstChild("Quests"))

-- Variables --

local Quest    = script.Configurations.Quest.Value
local Enabled  = script.Configurations.Enabled.Value

	local folder = Instance.new("Folder")
	folder.Name = QuestID
	
	local number = Instance.new("IntValue")
	number.Name = "Number"
	number.Parent = folder
	
	return folder
end

end)

how do i solve the error? i have tried many things but cannot get it to go away.

If it ain't broken, don't fix it.

Try changing the Variable name from Player to something else (Example: "plr", "dude", etc). I've had this error before aswell, and ROBLOX recognizes Player as a global variable, not a local one.

Hope this helps!

local Player = game.Players:FindFirstChild(part.Parent.Name)
if not Player then
	return
end

So it looks for the player in Players. If it dosen't find the player then it uses return to end the execution. Else, it finds the player and continues the code.
