ABarbuzzi,I have done this by putting a text box over the signature box
and having that text box disappear when the mandatory fields are
complete. I have gone as far as displaying text that states, "Until all
mandatory fields are completed, the signature field will not be
visible". By having the text box over the signature field, the user
can't sign the signature field as they are actually clicking on the text
box.I hope this helps,Joe
