Hi Linda, team:I have completed modofication of my custom form (ScottOrders) to have a VisibleGroup container for the @percent field, based on the @discounted boolean.However, I find that it doesn't work - form creates fine (and displays without the visibility attributes) - but when the form is added via nav hierarchy to use, the container does not show when checking the Discounted checkbox.Is the checkbox/boolean value evaluated "on check" ? or only after save ? (doesn't work for me either way ...
