my tween service wont move my platform what am i doing wrong?

im making a game based of the japanese game show the death pit and im making it so when a player says "ready" it will start. The first script is in ServerScriptService. Can someone help? Also the first script is a local script

game.Players.PlayerAdded:Connect(function(player)
	player.Chatted:Connect(function(message)
		if message == "ready" or "Ready" then
			game.ReplicatedStorage["Start Game"]:FireServer()
	end
end)

local TweenService = game:GetService("TweenService")
local PlatForm = script.Parent.Parent:WaitForChild("DisapearPart")
local tweeningInformation = TweenInfo.new(
    5,   
    Enum.EasingStyle.Linear,
    Enum.EasingDirection.Out,
    0,
    false,
    0
)
local Move = {CFrame = CFrame.new(99.125, 177.707, -262.83)}
local ComeBack = {CFrame = CFrame.new(99.125, 177.707, -215.915)}
local tween1move = TweenService:Create(PlatForm,tweeningInformation,Move)
local tween1comeback = TweenService:Create(PlatForm,tweeningInformation,ComeBack)
 
game.ReplicatedStorage["Start Game"].OnServerEvent:Connect(function(player)
    tween1move:Play()

    wait(70)
    tween1comeback:Play()

end)
