Are you looking at the view on the same server that the embedded view is accessing? If not, that's your problem. Is the view categorized? Is the embedded view set to show a single category? If it is, that's probably your answer right there

- Are you looking at the view on the web or in the Notes client?
- Same question for the document with embedded view?
- Was the document containing the embedded view created manually, or by script? (Show the code if it's the latter.)
- Was the document contained by the embedded view created manually, or by script. (Show the code if it's the latter.)
- Does it contain any Reader fields? Are you using the same ID to look at the view as you are
