giving rights selection rights to categories

I have Directory installed. While as administrator my access is healthy, as regular user my ability to enter listings is inhibited more than I would like. Specifically, I have pick-list choices for service and industry inputs that is grayed out for users to select as they input a new listing. How do I give rights to users to these selection fields?

In capabilities, I provided rights broadly to both subscribers and authors. I don’t see where else rights are handled. How can I provide these rights?

Please advise.

thanks,

Mark
