LIsting Setup>Custom Fields Display Order

Hello everyone. We use Classified Responsive Theme. We are having trouble managing the display order field when setting up custom fields while in the Listing Setup theme menu. There is a display order to be managed however we cannot find how the order is managed by number . Where can we see a list showing some type of display order count? If you have many custom fields, it is easy to lose track of the numbering count, and how is the count ordered after hard coded fields within the theme? Thanks for your assistance.
