That doesn't look like List View. It looks like Table View--which is a different kettle of fish.
In FileMaker 13, don't use conditional formatting for this. Use the new "hide when" property in the inspector.
Yes, I meant table view. By different kettle of fish I assume that the "hide when" property doesn't work in table view? Works beautifully in list view. Guess I'll change my report if that's the best alternative. Thanks!
