have a spread sheet with 70000+ rows.
each row has an unique id# and a dollar figure associated with it.
Each unique id# is repeated many times.

so if rows 1-50 had unique id # 2400 and each row has a different $ amount
and rows 51-100 had unique id # 2401 and each row has a different $ amount
and rows 101-121 had unique id # 2402 and each row has a different $ amount
and this pattern continues in a similar fashion for all 70000+ rows.

how can I  sum all $ amounts for each unique id# without breaking each id# into it's own worksheet?

You can do it several ways.  With Sumproduct or SumIf

=SUMPRODUCT(($A$1:$A$8=D2)*($B$1:$B$8))

 OR

=SUMIF($A$1:$A$8,D2,$B$1:$B$8)

Have a look at the attached sample.  The IDs are in column A, the dollar amounts are in column B, the unique id's (non repeating) are in D2 and D3 and the formulas are in E2:F3.
