Assign Variable

This action is only relevant to the Design view, where you can add the action to the canvas and use the Properties pane to visually select a variable and a value to assign to it.

In Code view, the syntax for specifying a variable and its value is:
$<scope>.variables.someVar = value;
For example:
 $page.variables.fullName = $page.variables.firstName + ' ' + $page.variables.lastName;
