Help with achievments

Heya! I'm making a club penguin-esque game, and i wanted to add achievments. But, the game does not add them to the achievment list.
This is the code:

(step event from player object)
if global.game1=1
{
if global.game2=1
{
if global.game3=1
{
gms_message_reporting(mt_achievement_get)
gms_achievement_reach("true_gamer")
}
}

The global.game 1-3 are some variables that come to 1 the first time you complete noe of the three current minigames, iot is suppossed to add the event if the three variables are 1, or i simple form, the player has played the three games. Also, the achievment is litterally called "true_gamer" and i have put it on the game editing on the web.

Thanks!

PD: The game don't present an error or anything, it just don't add the achievment
