Defining Flexfields in Framework Personalizations

 Can anyone give us an assis in showing our flexfields in the Purchasing UN Numbers form

we are confused with the following

1. Set the Name field to the parameter name of your flexfield. For example, if your Flexfield definition uses a named parameter $PROFILE$.*paramName, then set the Name property as *paramName.
2. Set the Reference Value to the value or value binding that will be set on the parameter. It can be a constant value or a SPEL of the form ${oa.page.<id>} where <id> is the id of the web bean on the current page that will act as the reference field.
