Well, this issue came up while doing your Real Estate Mailer tutorial that is supplied with the software install. It's found on the Mac at HD > Users > Shared > PTI > FusionPro > Tutorial > Real Estate Mailer > Working Files. If you open the PDF named "PresidioPostcard2.pdf", you'll see the variable data box that says "Come see us <Season>". The instructions in your video state that the Season rule should return Winter, Spring, Summer or Fall. But it doesn't work because the supplied sample source file "input-data.txt" doesn't appear to have any data regarding the months/seasons. I assume this is an oversight when creating these tutorials. You'll even notice that the sample PDF in the Output folder also does not include the seasons information.
My concern isn't so much that the tutorial appears to have a flaw in it, but rather the Compose error reporting between version 9.2 and 9.3. When I did this tutorial in 9.2, I received an error after clicking Compose that suggested there is no data for the Seasons rule, which is obviously very helpful. When doing the same tutorial in 9.3, I received no error message at all, which is not very helpful when trying to figure out why data is missing. We are planning to upgrade our systems to Yosemite/9.3 here at the office, but I'm now concerned that if we upgrade, we'll be losing a pretty useful error reporting function from 9.2. Does that help clarify what I'm asking about? I can send you files if you like, but again, I'm just using the tutorial files supplied with the install.
