Formatting

Well, the last part should be easy, right????? I wrote the novel, I edited the novel, I corrected the novel, I did a final proof, and now I have the format instructions from the publisher. Should be a piece of cake, right? Wrong!!! I am working on a new edition of Word--#10. It is wonderful, but I haven't quite figured and every time I try to change something, it changes something else. Ohhhhhhhh!!! Buggers! If anyone can tell me how to get an original header on the left side of every page, please feel free. LOL The publisher is expecting the manuscript so I have to figure it out soon. :D Wish me luck! Onward and upward.
