TaxesH__c => Public Hierarchy

  1. If you want to track new custom fields use CUTOM FIELDS SECTION.
  2. If you want to track just records use VALUES SECTION
  3. Hierarchy custom fields
  4. Hierarchy records

here it is small example. Taxes__c => Public List Custom Settings. Value__c => 1st custom field. Value2__c => 2nd custom field.

  1. If you want to track new custom fields use CUTOM FIELDS SECTION.
  2. If you want to track just records use VALUES SECTION
