As far as drupal 6 views 6.x is concerned. You need to ensure you are saving the taxonomy heirarchy as additional terms in the database. Ensure also you are saving the entire lineage from the view. Finally Add a filter with Taxonomy: Term ID and leave this using default values.
(1) Ensuring you are saving the taxonomy heirarchy as additional terms:
-edit your "Results" content type, go to manage fields and edit the heirarchical field. Somewhere on this page you will see 'Save values additionally to the core taxonomy system (into the 'term_node' table).'
(2) Ensure you are saving the entire lineage:
-on the same page as above follow the link to oonfigure this heirarchical select on a separate window.. 'Due to limitations of CCK, there is a separate form to configure this Hierarchical Select widget's settings'
(3) Go back to views and add that filter I mentioned above.
