Bookmarking not working

Yes, done it, but not trivial and the best it can do is tell the user they are doing it wrong and some data will not be recorded. It can't prevent the exit - at least not that I have been able to figure out.You have an On Hide Display action inherited on each page that DISPLAYS a message warning the user to exit properly. It only runs under the condition that a variable, let's say _exit_OK = noOn your Next, Back, and all other buttons that allow you to change pages, you have an action that first sets the value of _exit_OK = yes. That way, when they go to the next page it does NOT set off the warning. Follow this action with the button action of Next, Back, etc.But now on arriving at the next page, the variable is set to yes and you need it to be reset to no so if they click the X on this pg, it fires the warning msg. So, you have a second On Show action inherited on most all pages that sets _exit_OK = no. best I can do in a pinch.
