You can reference existing columns by specifying their names as you can see them in the user attributes preview window. The column names need to be enclosed in the square brackets. [{AttributeName}]
NOTE
The name of the attribute referenced in the script may not always match the display name (label) of the attribute as shown in the User Attributes configuration.
For example, if configuration page shows attribute as “User Location” the script is likely to refer to it as “[UserLocation]”.
NOTE
The display names (label) of the User Attributes might change. PowerSuite provides the ability to change the display name of the attributes. That doesn’t mean you will need to update the script. PowerSuite will retain the original name as used in the script allowing for continuity.
