Hi Jonathan,
You identified the problem exactly. I did not register the custom taxonomy in functions.php. If you had not told me how to do this and provided the snipped I would be lost, so thank you very much.
I would like to point out that to make the archive work for the custom posts types (with the custom Taxonomy) I had to select the correct Taxonomy in the custom Taxonomy selection box and ALSO check off the identical Category Taxonomy in the standard WP Catagories box. I am totally ok with this, but want to point it out to check and make sure this is ok and won’t bite me down the road.
Thank you for your help!
Daniel
