Why doesn't my RemoteEvent work?

I made a script that calls a RemoteEvent to determine what you are playing as. I put a value in the player's backpack so if it equals something you play as that character. But for some reason my RemoteEvent isn't working. Here is the script for calling the RemoteEvent.

	if Class.Value == 1 or
		Class.Value == 0 then
		game.Lightning.TestCharacter1.RemoteEvent:FireServer()
	end

and here is the script for the RemoteEvent

local player = game.Players.LocalPlayer
Folder = script.Parent
Event = Folder.IsChar1


script.Parent.RemoteEvent.OnServerEvent:connect(function()
				player.Character.LowerTorso.Transparency = 0
	
					wait(0.01)
		
			player.Character.Head.face.Texture = "http://www.roblox.com/asset/?id=591414447"
				
	local Sleeve = Instance.new("Part", player.Character)
	Sleeve.CanCollide = false
	Sleeve.Anchored = false
	Sleeve.BrickColor = BrickColor.new("Maroon")
	 Sleeve.Size = Vector3.new(1.11, 1.2, 1.07)
	local w = Instance.new("Weld", Sleeve)
	w.Part0 = player.Character.RightUpperArm
	w.Part1 = Sleeve
	w.C1 = CFrame.new(0,-0.36,0)
	
	local Sleeve2 = Instance.new("Part", player.Character)
	Sleeve2.CanCollide = false
	Sleeve2.Anchored = false
	Sleeve2.BrickColor = BrickColor.new("Maroon")
	 Sleeve2.Size = Vector3.new(1.11, 1.2, 1.07)
	local w = Instance.new("Weld", Sleeve)
	w.Part0 = player.Character.LeftUpperArm
	w.Part1 = Sleeve2
	w.C1 = CFrame.new(0,-0.36,0)
	
	local Tanktop = game.ReplicatedStorage.Union:Clone()
			Tanktop.Parent = player.Character
		 local w = Instance.new("Weld", Sleeve)
		w.Part0 = player.Character.UpperTorso
		w.Part1 = Tanktop
		w.C1 = CFrame.new(0,0.18,0)
		
			local UpPant = Instance.new("Part", player.Character)
		UpPant.CanCollide = false
		UpPant.Anchored = false
		UpPant.BrickColor = BrickColor.new("Really black")
		UpPant.Size = Vector3.new(1.08, 1.21,1.04)
			local w = Instance.new("Weld", player.Character)
		w.Part0 = player.Character.LeftUpperLeg
		w.Part1 = UpPant
		w.C0 = CFrame.new(0,0.25,0)
		
			local UpPant2 = Instance.new("Part", player.Character)
		UpPant2.CanCollide = false
		UpPant2.Anchored = false
		UpPant2.BrickColor = BrickColor.new("Really black")
		UpPant2.Size = Vector3.new(1.08, 1.29,1.04)
			local w = Instance.new("Weld", player.Character)
		w.Part0 = player.Character.RightUpperLeg
		w.Part1 = UpPant2
		w.C0 = CFrame.new(0,0.15,0)
		
		local LowPant = Instance.new("Part", player.Character)
		LowPant.CanCollide = false
		LowPant.Anchored = false
		LowPant.BrickColor = BrickColor.new("Really black")
		LowPant.Size = Vector3.new(1.08, 1.23,1.04)
			local w = Instance.new("Weld", player.Character)
		w.Part0 = player.Character.RightLowerLeg
		w.Part1 = LowPant
		w.C0 = CFrame.new(0,0,0)
		
		local LowPant1 = Instance.new("Part", player.Character)
		LowPant1.CanCollide = false
		LowPant1.Anchored = false
		LowPant1.BrickColor = BrickColor.new("Really black")
		LowPant1.Size = Vector3.new(1.08, 1.21,1.04)
			local w = Instance.new("Weld", player.Character)
		w.Part0 = player.Character.LeftLowerLeg
		w.Part1 = LowPant1
		w.C0 = CFrame.new(0,0,0)

end)

print("works")

^ is suppose to tell me if every part is welded to the player.

A Server Event should be fired in a local script and handled in a server script as I can see you handled it in local script which is wrong.

There is no need to make player variable because you get that variable by default using

RemoteEvent.OnServerEvent:connect(function(player) --- player variable

so basically FireServer() should be used in local script and OnServerEvent should be used in server script.

You're using the wrong functions in the wrong scripts. You're firing the server from a server script, and then connecting to a server event from a local script.

Here's a rundown of RemoteEvent functions:

Use on server scripts only:

• :FireClient(player) - Fires the event for only
• :FireAllClients() - Fires the event for all clients
• .OnServerEvent(player) - Fires when the event is fired from client

Use on local scripts only:

• :FireServer() - Fires the event on the server
• .OnClientEvent() - Fires when the event is fired from the server

Make sure you're using these right and your RemoteEvent should work properly.
