The variable's that can be used in a template vary based on the object currently in [scope](#scope). Scope defines what
object the methods get called on. For the standard `Page.ss` template the scope is the current [api:Page_Controller]

This is functionalty the same as the following:
:::ss
Hello, $CurrentMember.FirstName, welcome back. Yout current balance is $CurrentMember.Balance
Notice that the first example is much tidier, as it removes the repeated use of the `$CurrentMember` accessor.
Outside the `<% with %>.`, we are in the page scope. Inside it, we are in the scope of `$CurrentMember` object. We can
refer directly to properties and methods of the [api:Member] object. `$FirstName` inside the scope is equivalent to
`$CurrentMember.FirstName`.
<div class="info" markdown="1">
Why would you use `with`? This keeps the markup clean, and if the scope is a complicated expression we don't
have to repeat it on each reference of a property.
