The field names you may include in your Store Tags are essentially the same as the actual field names used in Catalog Manager and Store Editor. When used in Store Tags, however, field names should always be lowercase.

To refer to a custom field you have created yourself, use the name you provided for the field, in all lowercase letters, making sure to replace any spaces in the name with hyphens. (If you can't remember the name of a custom field, use the Store Tag Wizard to generate a Store Tag for the field.)

Here is the complete list of fields. The field name as it appears in Store Editor and Catalog Manager is on the left. The field name as it should appear in a Store Tag is on the right.
