Me type game Id to teleport people button dosen't work?

local GameIDType = game.StarterGui.ScreenGui.Frame.TextBox
local gamevalue = Instance.new("NumberValue")
gamevalue.Parent = game.StarterGui.ScreenGui.Frame
gamevalue.Value = GameIDType.Text
local TextButton = game.StarterGui.ScreenGui.Frame.TextButton

local TeleportService = game:GetService("TeleportService")

TextButton.MouseButton1Click:Connect(function(player) 
TeleportService:Teleport(gamevalue, player)
end)

Hope this works!

Doesn't work because:

You can't have a propety that is a string or a number for some objects that in a variable. For example: "example.Value", Instead, Write "example", and at another line the example's variable to add ".Value"

Hope this helps for your future projects!
