As you can see in the attachment, the first one (using the custom field for price) does not show the price tag, whereas the second and the third ones (using classipress built-in price field) show a price tag.
I need to have the two different price fields because some types of ads-categories are associated with huge currency values. That is, instead of displaying (10000000), 10 (M,million) for the price would make it much easier for the users to grasp the price.
How can I make the price tag associated with the custom (price) field appear on the price tag?
