How to get location of closest enemy pawn?

How would one go about getting the location of the closest pawn within a radius? I need the location to plug into a teleport for a special attack in my game. If someone could give me an example of the nodes to use, that would be great. I imagine I would need an array, but how I would get the location information is a little confusing to me. Also, when I “Get” from my purple array filled with actors, there is an empty plug with a number next to it. I do not know what to plug in there.
