 Parameters are the means by which you pass data to your page. When a page is loaded, the parameters are filled with the current values.

 ### Argument {#argument}
 
-The page has a parameter, which can be made required or optional. If it is required it is mandatory to supply an argument for that parameter when opening a page.
+Determines whether it is **required** or **optional** to [pass an argument](/refguide/page-parameter/#passing-arguments) to the parameter when opening the page. If it is required it is mandatory to supply an argument for that parameter when opening a page.
 
-#### Default Value
+### Default Value
 
 When an argument is set to **optional**, a default value can be set. When a default value is set if the parameter is omitted, the default value will be used. In the example below, if the parameter is omitted by the user an empty string `''` will be used for the parameter.

+## Passing Arguments {#passing-arguments}
 
-When using an **Show page** action form a microflow, nanoflow or button, you can pass arguments in two primary ways, depending on the data type of the argument.
+Arguments are passed to page parameters when a page is opened. For example, using a **Show page** action [on a widget event](/refguide/on-click-event/#show-page) or in a [microflow](/refguide/show-page/). For each parameter the page has an argument can be configured. It is only necessary to pass arguments to [required parameters](#argument).

 ### Variable Arguments
 
-Variable arguments are used to pass parameters from the context to the page. This is done by selecting the desired `arguments` from the dropdown. **Optional** can be omitted by selecting `(None)` .

-### Expression-Based Arguments (All Data Types)
+### Expression-Based Arguments
 
-Primitive values, such as strings, booleans, and enumerations, can be passed as 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 an parameter **AnimalName** which is populated by the **Name** member of the provided **Animal** object.
