To respond to a control value error
1. From the details pane (or Activity Data dialog box in a custom display), select the tab
containing the error icon. The number of errors within this tab is indicated in par-

entheses will decrease and the error description text for the updated parameter will be
removed. When all errors have been addressed there will no longer be an indicator of
