Hi Alexandre,

Sounds good! I get a 403 error however when clicking on the provided link. And have you considered adding your library to the online formula database?

I signed up, but I tried typing my password and it doesn't work! Something is wrong with the sign up process...

I do not know where I can upload it, aside from Google Drive...

I am also getting numerous errors, such as

Cannot find class declaration
Return expression not allowed

But for some reason, the cursor is not pointing out the exact problem, i.e. on the wrong line and column, so what is going on and why does it happen with plug-in library files?
