This custom chat doesn't work in real server.?

This is located in starter gui.It's a local script

local rep = game:GetService('ReplicatedStorage')
local startergui = game:GetService('StarterGui')
local uis = game:GetService('UserInputService')
local plrs = game:GetService('Players')
local chatevent = rep:WaitForChild('ChatRemote')
local client = plrs.LocalPlayer
local mouse = client:GetMouse()
local chatbar = script.Parent
local chatframe = chatbar.Parent
local chats = {}
uis.InputBegan:Connect(function(key)
	if key.KeyCode == Enum.KeyCode.Slash then
		chatbar:CaptureFocus()
	end
end)
local function pushmessage(size)
	for i,v in pairs(chats) do
		v.Position = v.Position - UDim2.new(0,0,0,size)
		if v.Position.Y.Offset < -chatframe.AbsoluteSize.Y then
			chats[i] = nil
			v:Destroy()
		end

	end
end
local function createmessage(message, speaker)
	local label = Instance.new('TextLabel')
	label.BackgroundTransparency = 1
	label.TextXAlignment = 'Left'
	label.TextColor3 = Color3.fromRGB(255, 239, 10)
	label.Font = Enum.Font.Code
	label.FontSize = Enum.FontSize.Size18
	label.Size = UDim2.new(0.8,0,0,20)
	label.Position = UDim2.new(0,0,1,-25)
	label.Text = tostring(speaker)..':'..message
	label.TextScaled = true
	pushmessage(label.Size.Y.Offset)
	chats[#chats+1] = label
	label.Parent = chatframe
	local wordList = {
	"null"; --Content removed by moderators.
	"null"; --Content removed by moderators.
	"null"; --Content removed by moderators.
   "noob";
   "Hello";
  "null"; --Content removed by moderators.   "idiot";
   "kick/";
   "ban/";
}
for i,v in pairs(wordList) do
	if chatbar.Text == v then
		label.Text = client.Name..' IS SWEARING'
	end
end
	
end

chatevent.OnClientEvent:Connect(function(request, message, speaker)
	request = request:lower()
	if request == 'chat' then
		createmessage(message, speaker)
	end
end)




chatbar.FocusLost:Connect(function(enter)
	if enter then
		chatevent:FireServer('chat', chatbar.Text)
		if chatbar.Text == '' then
			return
			end
			chatbar.Text = 'CLICK here or press SLASH to chat'		
	end
end)
startergui:SetCoreGuiEnabled(Enum.CoreGuiType.Chat, false)

this doesn't work in real server

local wordList = {
	"null"; --Content removed by moderators.
	"null"; --Content removed by moderators.
	"null"; --Content removed by moderators.
   "noob";
   "Hello";
   "null"; --Content removed by moderators.
   "idiot";
   "kick/";
   "ban/";
}
for i,v in pairs(wordList) do
	if chatbar.Text == v then
		label.Text = client.Name..' IS SWEARING'
	end
end

Also this script is located in ServerScriptStorage. It's a normal script

local rep = game:GetService('ReplicatedStorage')
local chatevent = rep:WaitForChild('ChatRemote')


chatevent.OnServerEvent:Connect(function(client, request, value)
	request = request:lower()
	if request == 'chat' then
		chatevent:FireAllClients('chat', value, client.Name)
	end
end)

It doesn't work, because after you fire to the server you clear the chat bar. Also, you are just attempting to clear the chat bar, not the message that everyone gets. My suggestion is just use Roblox's filter. Additionally, you are only checking if the chat bar text is EXACTLY that text. so you could easily bypass it with a character before, after, etc.

the wordlist table should be outside of the function
