 * Hi
 * I created a custom taxonomy (using register_taxonomy) for my attachments called‘
   document-category’. I then created two categories (‘Industrials’ and ‘Consumer
   Goods’) in this taxonomy and assigned some (pdf) attachments to them.
 * I then created a page, added the attachments to the page, and used [dg document-
   category=”Industrials”] to try and display only the pdfs with that category and
   received the following error on my site “document-category=”Industrials” is not
   a valid term name in 0.”
 * Am I doing something wrong?

 * Hi **bucklea**!
 * Unfortunately shortcode engine of WordPress doesn’t recognise appropriately parameter
   names with hyphens. So, please, define another taxonomy name, for example You
   can use _‘document**\_**category’_.
