Hello Nico,
Thanks for your reply. I added the snippet of code to the bottom of the functions file and it doesn’t seem to work quite right. The default Categories box appears on the edit event page but as soon as I select a category and select update, I receive errors.

I’m not sure what’s going on here. Thanks for your assistance. -Michael
