Trying to make something spawn certain number of times.

Hey, im trying to make a randomized amount of wood spawn after i knock down a tree, but I dont know how to make the actor spawn the amount of times I have it set in random. How can I make it spawn a certain amount of times?

I figured it out but they all spawn in the same place and it explodes and the wood all fall off the map. Is there any way i can make them spawn near each other or in a stack or something.
