Are you absolutely sure you did it right? Secondly, I would never even attempt to use this feature anymore. Even in Acrobat it's kind of wonky and won't work at all in many other browsers. If you tell us the effect you're going for maybe we can offer alternatives.
I am pretty sure it has been set up correctly but I think I am pushing capabilities too far. I have a multi-page layout set up on a single spread, that way radio buttons on the first page can show/hide elements on pages 2&3.
I am trying to create a checklist that helps with customer orders. Currently, we have two different extensive PDFs that are 4 pages each and I am trying to simplify and create them as one document. I set up the initial fields and they worked fine. I essentially copied them over and adjusted settings as needed but they are not cooperating.
