I have a content type "review" with a node reference to "product". I want to be able to have users rate the product while writing a detailed review. I added a Fivestar "rating" field in "review" and selected as "voting targed" the "node reference field". Users can enter the review and rate it at the same time. I created a view to show all the reviews for a product and it pulls the ratings nicely from the "rating" field.
However I can't get a view configured correctly to show an average rating for a product. I setup a relation with "Content: Vote results", left the "required" box unchecked, "value type" = percent, "vote tag" = "vote", "aggregation function" = "average vote". All the vote results fields come up empty.
What am I doing wrong?
