I am trying to add a player to a chat channel if they have a tool equipped, so for i have the following script. There is already a chat channel created and i can join it manually by typing /j Radio in the main chat window. When i equip the tool the script just prints equipped in the output window. 

local ServerScriptService = game:GetService("ServerScriptService")
local ChatService = require(game:GetService("ServerScriptService"):WaitForChild("ChatServiceRunner"):WaitForChild("ChatService")) 
local Tool = script.Parent


function Equip()
	print("equipped")

	ChatService.SpeakerAdded:Connect(function(PlayerName)
		print(PlayerName)
		local Player = game.Players:FindFirstChild(PlayerName)
		if Player and Player:GetRankInGroup(8370936) >= 190 then 
			print("Join the channel!")
			local Speaker = ChatService:GetSpeaker(PlayerName)
			Speaker:JoinChannel("Radio")
		end
	end)
end







function Unequip(mouse)
	print(" not equipped")
end

Tool.Equipped:connect(Equip)
Tool.Unequipped:connect(Unequip)
