Цитата:

The exception to this is when you define display on a form data source method. If you choose to write a display method on a form data source, you must include the data source as parameter, for example

PHP код:

display InventQty Accumulated(InventBudgetInvent Budget) 


which is a method on the data source for the InventBudgetInvent form.
