Joe, The I think two most common debug methods,
1. ask smaller questions. Put a filter in a list-links and check the results (use advanced Search Filter tab as well) 2. Use the browser inspect to see what was generated You can also provide a single tiddler name or title rather than a more complex filter to test the result if that tiddler name was generated by the filter.
