The normal flow of states is based on the next TaskScreen in the treeview, or the stated OKScreen or AddTargetScreen for Entry/Add or Auto-Select screens.
For data entry screens (Add/Update), this property can be set to override the next screen following a successful entry. This is provided mainly as a means to recycle back up the tree, as the search for the screen will start at the top of the tasktree.
If the same screen occurs more than once in your task, add the number 2 to the name for the second, 3 to the third, and so on.
