Thanks Eric, appreciate your fast response as always.
Using "word" works well as you can see on the page here
I think the brand must be there in the feed somewhere as it works fine as a filter in the store (and my brand filter widget is using query='brand=callaway')
I need to play with the css in the main wp style.css to get things displaying properly and somehow remove the store category title and breadcrumb from the top of the view (any ideas?)
I would like to explore further using php to generate dynamic category descriptions on the filtered store pages and also image names but am no php expert. Do you have any code that might get me started and I can edit a bit?
Any ideas will be welcome but I do now have a way of getting this started.
Thanks again, Keith
