In the Edit Formula window, the Groups page provides for selecting a group when the database function selected on the Functions page requires two parameters (Field,Group). The entries on the Groups page represent the Group Headers that are inserted in the Report Design file. For more information, see Inserting a Sorting or Grouping Criterion. Each entry is assigned an integer. To insert the integer for a group in the formula, you double-click an entry or use the standard Windows drag-and-drop technique. For more information, see Inserting a Formula.
