Yup - there's a Category_ID field. For these lists, once everyone has their country added, I think I can use a join in the main recordset to pull through the country. Going down that route I couldn't get it to include the cases where no country was added to the lodge_activities table. (That table should really just be called 'activities', or better still something like 'keywords', but it was originally supposed to be for activities at lodges, and its kind of grown from there, hence the slightly unintuitive lay names tables).
You originally helped out with the recorder within a recordset approach for lists of lodges which included two different activity categories, so couldn't both be included in the main recordset.
