Conditionally Change a Label's Text

This document describes how to display different values in a report control based on a specified logical condition.

    Use the Iif function to define the condition. For example:

    Iif([UnitsOnOrder] == 0, 'None', [UnitsOnOrder])

    This expression means that if the UnitsOnOrder data field's value is zero, the control's text is set to 'None'; otherwise, it displays the UnitsOnOrder field's value.

When switching to Print Preview, you can see the report control displaying the assigned values:
