BTT AI move to specifics target point

Hi every one ! I’m new in Unreal Engine 4 and reading this tutorial : https://docs.unrealengine.com/latest/INT/Engine/AI/BehaviorTrees/QuickStart/

But, in my project, i would like that my AI move to some specifics target points on the level. To do this, i’m creating a “BTTask Blueprint Base” called “BTT_AI_Forte_01_NextRoute” for moving my AI to the 4 specifics target points defined in my AI blueprint, but my AI doesn’t move when i launch the game.
The behaviour tree is still on the Update Route node (where “BTT_AI_Forte_01_NextRoute” is defined) and my AI stay at his spawn point…

Some screens of my blueprints :

Thanks
