it has been hard getting back to my document, probably because an icon has not popped up on my screen and the form is not in my laptop document file. it's not letting me add lines to the lists though that might be a hard lock in the form. However the section instruction's say that you can add. Mostly I have only used PDF filler on this complicated form and am learning by trial and error.
