Don't really want to put url on a forum
I tried your suggestion of creating a custom view . I called it Master Product Category (by mistake) but changed the DRF: to match this. I followed your other instructions.
However now when I go to my category page nothing at all shows up. I have set over 40 comparison sets. I believe this makes a product a 'master product'
Stuck now. I will email my url to you if you need it.
