Investigate the Display of Screens and Controls

In the left hand pane of the Interview view in the Debugger you can see which controls are currently shown (not grayed out) and hidden (grayed out).

The Details view for a screen shows why a screen has been shown or not.

For a screen that will be shown if it collects relevant information, you can click on the Relevant link to display the Decision view for that goal.

In the Decision view you have the option to show which controls on the screen are relevant to the goal you have selected and how. To do this, select the Show control paths only check box. This will filter the decision report such that only the paths influenced by a control on the screen will be displayed.

For a screen that will not be shown, you can click on the value link to display the Decision view for the attribute that controls the visibility of the screen so that you can set or change the value to see how this will affect the visibility of the screen.
