You may also want to consider the CurrentFieldValue keyword. By using CurrentFieldValue instead of the actual field name, is it easy to copy the formatting between similar fields using the Format Painter.

In your situation, the suppression formula would be

CurrentFieldValue=True

A neat trick to turn a Boolean value to Yes/No is to make use of the field's Display String property; it is also located on the Common tab. Enter the following formula:

IIf(CurrentFieldValue=True, 'Yes', 'No')
