Help please for a novice user.


I have ms office home & student 2007. Containing Word, exel, power point & one note. I wish to add Publisher 2007 but am confused as to whether I need to buy the full program or the upgrade. The implication on a couple of sites is that if I have Office I only need the upgrade. Please would someone clarify this for me. I have mailed Microsoft but had no answer. One of my sons insists I need the full prog, the other thinks the upgrade will do it, hence very muddled.
