In the manual the topic "Display Order" says: Navigate to the entity type being altered (categories in the example below) and click on the main entity heading.
Following the example, in the menu item "Manage Categories" I was able to drill down to Residential Signs>Real Estate Companies > Your Castle Real Estate > Directional Signs > Open House & Home For Sale Directional Arrows. So far so good.
Following the manual's instructions, the second-lowest page in that sequence, "Directional Signs" did have the capability of re-ordering its sub-pages "Home For Sale & Open House A-frames", "Open House & Home For Sale Corex", "Open House & Home For Sale Directional Arrows", and "Open House & Home For Sale Round Rods". So the instructions were working for this page. But that's not what I wanted most. I needed to change the product order in the next level down, the lowest page.
I went to the lowest page, titled "Open House & Home For Sale Directional Arrows". From there I tried clicking first on "Products", as the manual shows. But that showed lots of products which were not really part of Your Castle Real Estate>Directional Signs>Open House & Home For Sale DirectionalArrows. Not good!
Nevertheless, I clicked on "Bulk Products: Display Order" the way the instructions showed. This brought up only 4 products, 3 of which had nothing to do with the products under "Open House & Home For Sale Directional Arrows"! Again not good.
So how do I make the intructions work?
