Which type of remote do you use with this type of script? Would you use a RemoteFunction instead?

I have been trying to create an AFK command. Once AFK is said, it fires a remote that initiates the other script to add a forcefield to the character and change an overhead rank and name displayer to say AFK. Once they say it again, the forcefield is destroyed and their rank resets to what it said previously. The event works in Studio and Online Mode, but other players can not see the changes made to the player (i.e. Forcefield, AFK name). I'm pretty sure I used the wrong remote. (Ignore the "done" remote below.)

Firing Script (Located in Workspace):

local repStorage = game:GetService("ReplicatedStorage")
local remote = repStorage:WaitForChild("afk")

game.Players.PlayerAdded:connect(function(player)
	if player:GetRankInGroup(3445873) >= 2 then
		player.Chatted:connect(function(msg)
			if string.sub(msg, 0,4) == "!AFK" then
				print("Noticed AFK said")
				remote:FireClient(player)
				print("Fired")
			end
		end)
	end
end)

Local Script Receiving Event (Located in StarterGUI): (Has two children: BoolValue called AFK and a StringValue called Original)

local afkRank = 2
local repStorage = game:GetService("ReplicatedStorage")
local remote = repStorage:WaitForChild("afk")
local uAFK = script:WaitForChild("AFK")
local doneRemote = repStorage:WaitForChild("done")

remote.OnClientEvent:connect(function()
	if uAFK.Value == false then
		print("Not AFK")
		Instance.new("ForceField",game.Workspace:FindFirstChild(script.Parent.Parent.Name))
		local playerModel = game.Workspace:FindFirstChild(script.Parent.Parent.Name)
		local rankGUI = playerModel:FindFirstChild("Rank")	
		print("Found the rank thing!")
		local original = rankGUI.Frame.TextLabel.Text
		rankGUI.Frame.TextLabel.Text = "AFK"
		print(original)
		script.Original.Value = original
		uAFK.Value = true
	elseif uAFK.Value == true then
		print("AFK")
		local playerModel = game.Workspace:FindFirstChild(script.Parent.Parent.Name)
		local rankGUI = playerModel:FindFirstChild("Rank")	
		print("Found the rank thing for turning back!")
		rankGUI.Frame.TextLabel.Text = script.Original.Value
		playerModel.ForceField:Destroy()
		uAFK.Value = false
	end
end)

Do I need to use a different remote? Please help! Thank you.

Hello wowie! I am here to answer you. You have been placing the right event. You should use a RemoteEvent in that situation. :)
