How can I set a field in a PDF form to automatically update with the entry in another field. I need to do this for both free form and numerically formatted fields.
Can you be a little more specific about what you mean by 'automatically update with the entry in another field'? That could be interpreted different ways, each requiring a different solution in the PDF. Do you want the fields to share the same value? Do you need a calculated value? Do you need to set the value in field A using a matching value from the entered value in field B?
