I have a form with multiple signatures, for example a Purchase Requisition form... the author needs to buy something so he fills in the form with the product he needs to buy that is worth X amount. He signs it and sends it on to his manager for approval, his manager signs it and sends it on to finance for approval signature. The author now receives this form back with all the signatures he needs, but now he can clear his signature therefore unlocking all the fields so he can change the amount to XX and resign so now it looks like he has a purchase requisition that is approved for XX with everyones approval signatures still in place... How can I stop this from happening? Can I lock certain fields with the second signature that stays locked irrespective if the author clears his signature or not. Or can I disable the 'clear signature' option after signing? If the author clears his signature, can it clear ALL signatures on the form as if resetting all signature fields so they are forced to sign again? Is there ANY way to get around this? Pleeeease help, I can't seem to get this right. I'm using Acrobat 8 Pro to create the form.
