i dunno if this is the right place to post about the NDS version of Assasins creed but i couldnt find anywhere else.

Well, straight to the point, in "The running Wind" chapter there is a part where ur in the sewers and you have to meet with Adha, she gets stuck and asks for your help to croos and after jumping on some logs i get a green arrow pointing at 2 guards, i take them both out but then there's no green arrow just 3 buttons to press, no boxes to press them all at the sametime and i've tried any combination pressing them in different order and nothing would happen and i dunno where to go, wherever i jump i just drown and drown, can any1 help me ?
