Using Dataview but I'm doing something wrong

Many questions:

  1. Vaults or folders? How many ‘Obsidian’ are open? If you have only one with FOLDERS inside named “Testbed” and (other one), these are folders, not ‘vaults’!
  2. How you create your fields (module, dueDate, rank)? Inside a frontmatter or inline fields?
  3. FROM selects the source from “folders”, “tags” and “links”, not “vaults”.
