I'm in a custom taxonomy page and I need to display all the options of a particular custom field called "Region". I tried doing a database query for all the possible values, however because multiple regions are selectable in the custom field, the resulted values are the many different combinations of regions (such as "Asia, Africa, Europe" as one, "Central America, North America" as another and "Europe, Central America", etc etc.)
I want to retrieve just them just singularly, ("Asia" as one, "Europe" as another, etc. etc.) How would I go about doing this?
