 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.

 ### Default Value
 
-When argument is set to **optional**, a default value can be set. The default value is used if no [argument is passed](#passing-arguments) to the parameter. Given the example below, if no argument is passed for **CustomerName**, the page will open with the parameter set to `''`.

 The default value is used when the argument is omitted during modeling. Not when the argument value is `empty` during runtime.

 ## Passing Arguments {#passing-arguments}
 
-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 from the available variables on the page presented in the dropdown. **Optional** parameters don't require an argument and can be omitted by selecting `(None)` .

 ### Expression-Based Arguments
 
 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:
