Hello,I want to show the user filling out a PDF form some instructions (or some information) if/when they select a certain value from a drop-down. The information is more than the app.alert or FormCalc's message window will show. Is there a way to have a PDF form "popup" via JavaScript? I want the instructions to be part of the fillable form but don't want it to print if they print the form and shouldn't be visible until if/when they select the value. I can show/hide fields on the form via JavaS...
