Displaying Last Page With Condition (SMARTFORM)

Hello experts!

My requirement is that I need to show the last page of my smartform, but only if certain flags are set. I've already checked some of the threads in the forum, but I don't quite understand most of the instruction.

So far, what I did are the following:

1. Create page LAST with the Next Page set to "blank"

2. Set conditions in the windows in the LAST page so that they appear only if the flags are set

When I try running the form the last page does not appear, even if the flags are set.. Please, can anyone help me on this one?
