Mapping an Identifier's Value to a Question
                                                    Use an attribute to display the current value of a variable in a Read Only Text question. Each time a postback occurs, the read-only text will update to reflect any changes to the mapped variable.
Implementation:
- Switch to the Definition tab.
 - Select the intended Read Only Text question.
 - Right-click the selected question.
 - Select Attributes.
 - Add a new attribute with the type Mapped to Variable.
 - Switch to the new attribute's Value panel.
 - Use the Attribute Value field to specify the name of the variable whose value you want to display.
 - Click OK.
