Gui created in LocalScript isn't showing up?

I am making a gui in a local script for simplicity reasons and trust me it is better for me to do this but the problem is that the gui won't show up, their is no errors, the local script is in startergui. I will copy/paste the script here and sorry if it's huge but I'm pretty sure you don't need to read all of it.

Player = Game.Players.LocalPlayer
Player:WaitForDataReady()
wait(2)

Thanks for your time! :D

Line 2, where it says Player:WaitForDataReady(). That command will never finish executing because any reading or writing of player data can only be done from Server-Side Scripts. Which means that Player:WaitForDataReady() won't work either. It won't give you an error, it'll just yield your script forever.

A better replacement would be repeat wait() until Player.Character. This'll yield the script until the Character has loaded.

Hope this helped!
