The "SUM" when I add a nunber of figures and use the "SUM" it will total but
if I add another number to it, it will not change the total sum. I've tried
every way and the total sum still doesn't change. It just doesn't add
automatically. I never had any problem with WINDOWS 98. Now I'musing
WINDOWS XP.

What am I doing wrong?

Is Calculation currently set to Manual? If so, after changing a cell you'll see "Calculate" in the
Status Bar.
Try hitting F9 and see if your Sum changes.
If it does, go Tools/Options go to the Calculation Tab and set to Automatic.
