I have a drop down list that is populated using an MS Access table. It works great in Pro, but even with usage rights extended in Reader, the list disappears when opened with Reader. What do I need to do to make it available to those using Reader?
Those are the rights that are set in Acrobat ...is that where you are setting it or are you using the LiveCycle Reader Extensions UI (going to a url and getting a screen where you can choose the rights to set)?
Ok sounds like you are extending the file using Acrobat. That does not turn on the ability to do database access on your form. The LiveCycle server Reader Extension product does that. You can get a trial version off of the developer site but remember that it is a server product....so unless you are familiar with server software you will probably struggle with the install.
