I have created a form and want to be able to Click a button and for it to save in a specific location with the getField("ASSOCIATE NAME").value + " " + this.getField("Date Completed").value + " " + this.getField("Time").value + ".pdf")
Where do I put this Java script and how do i make the button run it?
You can't do that. You can either save the file silently under a name you specify (this requires running the code from a trusted context, though), or you can open the Save As dialog, but then you can't specify what will appear in it.
What you can do, though, is display an alert window first where you let the user know under what name to save the file, but you can't force them to actually use it.
PS. In the future please post in the Acrobat forum.
