Hello Felix, I sincerely apologize for bothering you. Your assistance with my previous question was immensely helpful. Currently, I am trying to use a separate subflow for each operator to allow Operator1 to move through Queue1, Queue2, and Queue3 individually before consolidating the results and transferring them to Queue4. I attempted to set up an additional subflow, but I am stuck at the unloading stage as I am unsure how to reference the total number of items gathered from the three queues earlier. I hope you can help. Thank you.
