Hey @CyberPanda1670!
So you’re binding the event “spawn another_Event” to an event somewhere on a BP_Item_Interact called “Spawn Another”. So you need to call “Spawn Another” from the BP_Item_Interact, AND this will only work on the first actor of class found.
Then again, you have told us that you want it to randomly spawn an actor, but we will probably need more context to help you. 
something just not happening is a lot harder to figure out than something is happening, just happening strangely, if that makes sense.
Get back to us with some more context! 
Maybe show that event that you’re binding to, as well?
