I have a classifieds ad script. It allows the creation of customs fields. Each custom field can be assigned to work with any or all categories that you specify.
The script has one bad feature. It has a default price field that works with ALL categories. You cannot select it to work with just some of the categories. The only option it has is to either turn it completely off so that it does not show up in any categories, or to turn it on so it shows in ALL categories.
I would like to have this particular field to be modified so that you can select it to work with any category that you assign it to.
