Custom Behavior Tree Task Not Working

I’m creating a basic AI behavior tree right now and the custom task I made isn’t working when I play the level. What I’m trying to do is make a simple ai that moves to a random location in a nav mesh. I made the character bp, ai controller, blackboard, behavior tree, and custom task for the behavior tree. I attached some screenshots of everything in question, and also linked the tutorial I was following which would explain everything I’m doing step by step.

Acutally, I figured it out. Simple mistake was not setting the blackboard key to target location instead of self actor as shown. Therefore, the behavior tree didn’t know what to do.
