the last step in all this would be to place your actors in the level and set the rings variable. if you look at the picture below the raptors are my rings and the highlighted box is my speedrush bp. so to set the variable (make sure you checked the eye icon in the bp next to the variable name on the bottom left) just place your speedRush actor in the level in the same place as your first ring in the set. then with it selected go to the details panel and look for your variable, then click the + sign for as many rings as you want to add and set the value for each via the dropdown.
hope this helps set you on the right track.
