You win the prize for longest if/then/elseif block in AI2 history.

Now is the time to learn lists, files and the lookup in pairs block.
That should have been loaded from a Media csv file at startup.
Your lookup would cut blocks by 99%.


comment on fait avec les listes ?

There is a free programming course here and the aia files for the projects in the book are here:
How to do a lot of basic things with App Inventor are described here: .

Also do the tutorials to learn the basics of App Inventor, then try something and follow the Top 5 Tips: How to learn App Inventor
