Hello,
Looks like “Get All Actors of Class” in your first screen shot is never going to be called since its not hooked up to anything. That will feed a null value into your “click” function so it won’t run.
You may want to have the nodes that are after “Get All Actors of Class” between the click event and the click function.
Hope this helps!
