Using the mouse, you can drag either a formula variable from the
Formula Variable dialog or an operand from the
Formula Edit dialog and drop it on the simple operand to be
included with it in a new compound operand.
This creates a new compound operand containing the dragged item and
the operand on which it was dropped, with a default operator.
Note: If you drag the Total of Value Label variable from the Formula Map, a dialog box
appears showing the list of names and descriptions for the value labels available.
Select a value label and click OK.
The Formula Display dialog is updated to
display your modified formula.
