Can totals from 3 columns be carried over auto

[nje]

I have attached my workbook. Is it easily possible to get the totals from 3 individual columns (N.O.P) to be carried over to the next sheet by either ( there could be proper terms for what I want but I don't know them) typing something into a cell like a trigger for it to work or perhaps some other way. I would like if possible to send the totals of those 3 columns into there respective columns on the next sheet and so on, but not on a specific date, more on demand if you get my meaning. If it can't esily be done by me (a novice) then I can always type them in as necessary. I've just order the excel 'all in one' for dummies book, so hopefully will be less reliant on others who spend time helping me.
I have done this in excel 2010 but saved it and uploaded it as excel 2003 because the computer it will be on doesn't have the latest version. Thanks
