Help Creating Language Buttons

I'm nearly finished with my UFE game after several years of development.

I want to make buttons on the Options Screen or Main Menu screen to select a language, but am having trouble figuring out the code.

I have already added the languages in the UFE editor, but I need help adding the several lines of code to the game to make it work.

Can someone please help me out with this? Just let me know what I need to copy/paste into where.

Looking forward to chatting.
