Display DFF on Supplier Profile based on Condition

Summary

Display DFF when Supplier Type = 'Federal'

Content

Hello,

I've seen many posts regarding conditional display of Descriptive Flexfields.  However, I am unable to get it to work.

On the Manage Suppliers screen, we have a DFF with two segments.  I would like to display those segments only when the Supplier Type is 'Federal'.  I opened a sandbox and used page composer on the show component section for the flexfield segments.  I want to display the entire region when the Supplier Type is 'Federal'.  Below is the groovy expression I've tried but it will not work.

#{!(bindings._FLEX_NumOfVisibleSegments.inputValue == 0)} and
