I don't currently allow page ranges that go backward (i.e. 5-4), but I think you are right that I used to accept them. My parsing code correctly flips page ranges like that, but my validation code does not. I can fix this for the next update. Having said that, if you want to have separate page regions, they are expected to be separated by commas. So in your example, it should be "2-3,5-4", not "2-3-5-4". My code is not catching this error right now, so I'm going to have to fix that. If what you intended was pages 2 through 5, then page 4, that should be 2-5,4.
