Okay I got to work, it was stuck or something, I mean it doesn’t take a Rocket Scientist to get at least the gist of how it works, right? I knew something wasn’t quite right when you didn’t show me anything out of the ordinary. Maybe it was my “item” count of 1,000 that I then dropped to 500 and then(once again) went up to and changed “Match All to Any” of the following Rules - which it does need to be on “Any” for the two entries in my case: one for pop and one for rock.
Thanks for the response, I at least knew I had to reverse engineer things from my end :)
