Sharon,
Here is a link for you. I have 2010 and I was working on trying to make a blank word doc with the margin set for you, but before I did I wanted to share the link and follow up with you in the morning,
Two things do you already have data in a document and what version are you using?
Ok here is the link and I will check back tomorrow.
Don
