How do I create a chat-activated teleport within a place?

Coordinate = CFrame.new(14.3, 0.5, 37.4)

game.Players.PlayerAdded:Connect(function(P) -- Check when a new player joined
    P.Chatted:Connect(function(Msg) -- Check if person chatted
        if string.lower(Msg) == "lol" then -- Check if they chatted our keyword "lol"
            P.Character:SetPrimaryPartCFrame(Coordinate) -- teleport them
        end
    end)
end)

I encourage you to use SetPrimaryPartCFrame instead of setting the CFrame of a part on the player, The coordinate I took was a part position and turned it into a CFrame for it to work.

Roblox Player Chatted

local Players = game:GetService("Players")
local Teams = game:GetService("Teams")

local tpCommand = "/teleport "

local function onPlayerChatted(player, message, recipient)
  if message:sub(1, tpCommand:len()):lower() == tpCommand:lower() then
    game.Workspace.Player.HumanoidRootPart.CFrame = CFrame.new(Vector3.new(0, 50, 0))
  end
end

local function onPlayerAdded(player)
  player.Chatted:Connect(function (...)
  onPlayerChatted(player, ...)
  end)
end

for _, player in pairs(Players:GetPlayers()) do
  onPlayerAdded(player)
end
Players.PlayerAdded:Connect(onPlayerAdded)

Just ripped and re-wrote, you need to replace the CFrame with yours obviously.
