Using the Formula Field
Field Description
Using the Data Designer
Caption Enter text to describe this item on the data entry screen.
After you insert this field onto the screen, you can use
eWebEditPro+XML’s formatting capabilities to modify
its size, font, color, and other attributes.
Note: The Caption field only appears on this dialog
when you create the Calculated field. If you later try to
edit the field, the Caption field is not on the dialog.
However, you can edit the Caption text within the editor.
Data Style See ”The Data Style Field” on page 218
You can copy a sample calculation into the Formula field by
clicking the Examples field and selecting an operation from the
drop down list. For example, if you click on Examples Add two
numbers (X+Y), {X}+{Y} appears in this field.
Next, replace the variables with fields on the screen. Be sure to
select the curly brackets ({}) as well as the letter between them.
Then, when the user enters data into those fields, the calculation is
performed using the current field values.
If a calculated field tries to perform a numerical calculation with a
value that is blank or contains letters, NaN appears in the field. (NaN
stands for "not a number.")
If a calculated field tries to divide by zero, Infinity appears.
