A bug in the editor?

I've been trying to use playergroup and unitgroup array variables but they just don't seem to work.

I tried to test it":
Player Group - Add Player 1 (Red) to gyilgil[3]
Player Group - Add Player 2 (Blue) to gyilgil[3]
Game - Display to Player 1 (Red), at offset (0.00, 0.00) the text: (String((Number of players in gyilgil[3])))

But this gives out the valua 0 while it should give out 2. Is it me or..?

Thanks for time blablabla, Remy.

Go to the variables dialog and change their max array index to 4
