Using the Data Designer
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.
If the user does not replace all variables with a field or a number, when the
content is validated, validation will fail.
To do this, follow these steps.
1. Select the first variable to replace. To continue the example,
select {X}.
2. Click the Select Field button. A screen appears listing
appropriate fields on the Data Design screen.
3. Select a field to replace {X}. When you do, the field name
replaces {X} in the Formula field.
If a variable appears more than once in a formula (for example, {X} * number(
{X} <= {Y} ) + {Y} * number( {X} > {Y}), you only need to replace
the first occurrence it - eWebeditPro+XML will replace the subsequent
occurrences for you.
