How can I make a button to return to the main menu

[Karrion]

My game currently has 2 "main menus", one ingame, that you access through a button, in the main novel screen, and another one that is the one shown at the beginning of the game. I want to make a button inside the first menu (the ingame one), to return to the second main menu (the one at the start), but I don't know how to do that. I've tried various Calls and ShowMenus but none seem to work. Call "start", "main_menu" and "renpy.full_restart" result in a crash that says that can't find those labels. Any ideas?

Also, using Return() closes the ingame menu and returns me to the normal novel screen.

Thanks in advance.

Edit: Apparently I can't read and there is a function called MainMenu() that I didn't see in the documentation *facepalm*

Ah yeah, might want to prompt player to save before returning to menu too

The MainMenu() function also covers that, thankfully.

Oh, good to know. Wasn't sure.
