Sorry - i'm a complete novice at any kind of scripting. I tried the scripting you gave me - but couldn't get it to work. I replaced "docfileName" with "On-Line Booking Form" and "Hello World" with "Date" - this is the field I am trying to make mandatory. What am I doing wrong?
I'm creating the form in Adobe Acrobat from an InDesign document and don't see any "Form Properties". The only properties I see are the text field properties, and in this the "validate" dropdown. Are you able to help me with this?
