Working on a behavior tree and I've encountered a roadblock.
I'm currently working on a behavior tree described in this tutorial https://docs.unrealengine.com/latest/INT/Engine/AI/BehaviorTrees/QuickStart/14/index.html and I'm trying to put the tree together. While putting the completed "AggroCheck" into the tree, it isn't allowing me to change the TargetToFollow or TargetLocation. It just leaves me with a box that says "none" and I can't click on it to change the variable. I actually remade the blueprint from scratch and tried that again with the same result. Is there a common error that I'm doing wrong? I've double/tripple checked the AggroCheck blueprints and nothing seems to be wrong, everything is in the right place. Not sure what's going wrong.

In the Blackboard, make sure to expand the "Key Type" property of TargetToFollow and TargetLocation and select "Actor" as Base Class.

Go into your Behavior Tree that you set up. Then over in the details panel, set your Blackboard Asset to your Blackboard that you set up. This should allow you to fill in the slots that were blank. This worked for me.
