my first local script?

--Created by PenguinAnonymous (ttyyuu12345) Editied by Dittoide
--What's Added To M2S with Dittoide's Edit?
--/ Better dummy script function to improve compatibility (makes it like you are running the code inside the script.)
--/ Removed Gui In Bottom-Left for when you are making guis.
--/ Removed "Inserting Map Please Wait" gui when selected Workspace as Place to export.
--Credit: PenguinAnonymous for making original script, i just wanted to iron it out to my liking.
--Errors:
