local scripts not functioning as is and i dont know whats wrong?

Hello, so basically what im trying to do is make a script where you press a button then it makes a person invisible or visible and based on their stats they are invisible or visible. so if the client is invisible then if they have less stats then another client they are semi invisible to the other client but if the client has more stats then the other client then they are completely invisible to the other client. i have a server script and 2 local scripts that do this whole function process. 1 local scripts in the character which listen for the key pressed and fire a function to all clients.

local script #1:

local player = game:GetService("Players").LocalPlayer
local mouse = player:GetMouse()
local char = player.Character
local db = true

game:GetService("UserInputService").InputBegan:Connect(function(input, gameProcessedEvent, event)
	if gameProcessedEvent then return end
	if input.KeyCode == Enum.KeyCode.V and db then
		db = false
		print("Working")
		game.ReplicatedStorage.Events.INVISIBLITYYY:FireServer()
		if char.Head.face.Transparency == 1  then
			print("invisible")
			for _, Part in pairs(char:GetDescendants())do
				if Part:IsA("BasePart") or Part:IsA("MeshPart") then
					Part.Transparency = 0
					char.Head.face.Transparency = 0
					char.HumanoidRootPart.Transparency = 1 
					local vision = "visible"
					script.Parent.Vision:FireServer(vision)
				end
			end 
		elseif char.Head.face.Transparency == 0 then
			print("visible")
			for _, Part in pairs(char:GetDescendants())do
				if Part:IsA("BasePart") or Part:IsA("MeshPart") then
					Part.Transparency = 0.7
					char.Head.face.Transparency = 0.7 
					local vision = "invisible"
					script.Parent.Vision:FireServer(vision)
				end
			end   
		end
		wait(.5)
		db = true
	end
end)

this script listens for the key and makes the character invisible locally and fires a event with a variable called "vision" witch can equal either "invisible" or "visible".

next is script #2:

local character = script.Parent
local Players = game:GetService("Players")
local player = Players:GetPlayerFromCharacter(character)


script.Parent.Vision.OnServerEvent:Connect(function(plr, vision)
	game.ReplicatedStorage.Events.INVISIBLITYYY:FireAllClients(plr, vision)
end)

this simply gets the event and fires it then to all other clients with the plr and the vision variable.

local script #3:

game.ReplicatedStorage.Events.INVISIBLITYYY.OnClientEvent:Connect(function(plr, vision)
	local char = plr.Character
	print(char.Name)
	local stats = plr.stats.Phychic.Value
	local MyPLR = game.Players.LocalPlayer
	local MyStats = plr.stats.Phychic.Value
	print(vision)
	if vision == "visible" then
		for _, Part in pairs(char:GetDescendants())do
			if Part:IsA("BasePart") or Part:IsA("MeshPart") then
				Part.Transparency = 0
				char.Head.face.Transparency = 0
				char.HumanoidRootPart.Transparency = 1 
			end
		end 
	elseif vision == "invisible" then
		if MyStats > stats then
			for _, Part in pairs(char:GetDescendants())do
				if Part:IsA("BasePart") or Part:IsA("MeshPart") then
					Part.Transparency = 0.6
					char.Head.face.Transparency = 0.6
					char.HumanoidRootPart.Transparency = 1
				end
			end 
		elseif MyStats < stats then
			for _, Part in pairs(char:GetDescendants())do
				if Part:IsA("BasePart") or Part:IsA("MeshPart") then
					Part.Transparency = 1
					char.Head.face.Transparency = 1 
				end
			end   
		end
	end
end)

this local script is inside of playergui and it listens for the fireallclient and then it gets its player and the player that fired the function. it gets the clients stats and the player who pressed the keys stats it then compares and makes them either invisible or visible by checking stats and the variable named "vision".

hopefully someone can find the problem i am making or maybe my script has no problems and it isnt placed in the right area. well thank you in advanced!

Maybe try putting the scripts in StarterGui? That sometimes works for me.

Try doing a for I, player in pairs(game.Players:GetPlayers()) do then looping through all the players and checking that all on the server? May work.
