Adding columns

[Debbie]

my problem is my totals on my invoice are cents off. Some totals are right to
the penny, while others are short by several cents.

hi
this is a common problem in spreadsheet. it due to roundoff. check the
column of numbers that you are add to see if all numbers are exactly 2
decimal places, not rounded to 2 decimal places. i'll bet that due to the
numbers NOT being exactly 2 decimal places is causing you to add a half penny
here and there which causes the semmingly errornous total at the botton.
