dynamically produce a value for a report item in place of a hard coded
value. The Edit Expression dialog provides a list of predefined and
dynamic elements that can be used in your expression. A list of expression
element categories is located in the lower left hand list of the dialog,
the elements for each category are located in the lower middle of the dialog,
and descriptions are displayed in the lower right hand of the dialog.

or double click the list of elements in the bottom middle list to add them to
the expression. In the figure below an expression with two database Fields
