Hey ! 
I've seen a thread answer by an admin who said functions were useable on aternos just by going on the files and doing the same process as the one you would do if you were to add functions to a solo world so I rushed to do so and after adding every file I had to add and doing everything that is required, I still can't use the function I created when I'm in game... 
Can somebody tell me if there is something I should do to fix my issue and be able to use functions please? That would awesome!
Thank you in advance!
