Two for sure dumb questions, why have a column "D" if coulmn "A" is for
accounts,column "B" is for corresponding dollar amounts and column "C" is for
the results of sumed account values? Do you hit cntrl shift enter first on a
cell then enter the formula?

INDEX(IF(ISBLANK($A$1:$A$20),"",$A$1:$A$20),MATCH( 0,COUNTIF(C$1:C1,$A$1:$A$2
0&""),0)))

which is an array formula, it should be committed with Ctrl-Shift-Enter, not
just Enter.

Copy C2 down as far as you need

D1: =SUMIF(A:A,C1,B:B)

and copy down

I have column A that contains many account numbers and i have column B
which
is a dollar value that corresponds to each account.

A B
10023 $25.00
10024 $20.00
10025 $25.00
10023 $25.00
10026 $25.00
Is it possible to assign cells in column C to sum the amounts which equal
the accounts. For example account 10023 sums up to $50.00 and i would like
each time the account of 10023 is entered into column A ,it would
accumulate
the amount in a cell of column C .........can this be done?
