Currently working through the guide and on section 9 I don't know what I'm doing wrong in exercise 9.1.1. It says that after running the process I need to open the properties of the Data Items to see their current values but there are none. No mention beforehand of populating with my own values but even when I do that I can't get it to work. Also when I go to Control Room as specified in exercise 9.1.2 I can't see any items in Queue 1. I've followed the guide really closely so unsure what I'm doing wrong
