The blackboard key selector is a variable. You’ve named it the key that you want it to select, but you have to set the value in your Behavior Tree (the decorator), which will automatically let you pick from the keys that you actually have. If you don’t do this, it won’t work. You can also use the ‘Perform Condition Check AI’ function which will automatically give you both the controller and pawn in the node.
