Hello everyone!

A few days ago I did a memory match game:

I solved any problems with the help on this thread:

And upload the final capx version here:

But I can't do a especific connection with Facebook even using the official documentation. Currently I can make a connection but it doesn't seem to do anything, I can't share high scores or put an advertise in wall's player.
