How to make AI targetLocation of another AI?

Hey Thanks Evil.I really appreciate it. Okay so tag where and how? Examples and or videos are a big help. Attached u will see I tried get all actors of class and filled the info for the array but it still wont attach to the transform. I also tried casting to the AI but still no go. I also tried to plug it straight in from the event but still no go. My AI is using a made enemy controller not base AIController. Could that be the problem? I tried to cast to enemy controller but thats a no go too. What node to i plug in the transform to make Friendly target the AI? Thank you.
