In general, arguments are taken from any enclosing data widget. If the data widget enclosing the widget calling a page is inside another (nested) data widget, then objects from that data widget and any others in which it is nested can also be passed.

 ### Expression-Based Arguments
 
-Objects and primitive values, such as `Boolean`, `Date and time`, `Decimal`, `Enumeration`, `Integer/Long`, and `String`, can be passed and used in expressions. This method allows users to use functions and follow associations within the expression to set the argument values. Using expressions for arguments provides flexibility in setting values and improves the functionality of pages. In the example below, the page has a parameter **AnimalName** which is populated by an expression extracting the **Name** member of the provided **Animal** object:

 A page parameter is an input that needs to be passed from the calling page, microflow, or nanoflow to the current page. Page parameters determine information that can be reused on the page. For example, if you want to build an **Employee_Details_Edit** page, the page will have a parameter **Employee**. Thus when this page is called an Employee object needs to be passed to it to show the corresponding Employee data.
