Hi, Shivam. Thanks for your response and instructions. This didn't work for me--I think because my organization is not part of an agreement to have a third party validate electronic signatures. I was looking for a way to show approval signature on an internal policy without having to print the document, obtain the signature, and scan the signed document. It seems that in my situation, the best solution is to have the document lock down when the user adds an image of his or her signature with "Fill and Sign" signature button. If anyone has other ideas for no-print ways to indicate approval on internal documents when your organization hasn't yet committed to a digital signature program, I would love to hear about them. Thanks. --Sarah
