Example, from a list of several buyers who place orders on a regular basis, I
want to know how to write the formula in another table that adds the daily
inputs and totals it for the specific month, for a particular buyer. So if I
input the purchases of the day for 12 different buyers, if I want to check
what a particular buyer has bought for the month, it will be in another
table, but only the total to-date.

Hi
I'd try using a pivot table for this. See:
